a53729a704 fix(frontend): park uploads that cannot succeed, and stop two false signals
The upload queue gains `parkedFor`, so a photo rejected for a reason that cannot change on
its own stops re-pushing itself. A ban used to come back as a generic `forbidden`, which
purged the blob and moved the row to `blocked` — a terminal state with no retry button — so
lifting a ban restored everything except the photo actually in flight. Ban and release are
now distinct codes that keep the blob, charge no attempt, and tell the guest what has to
happen. `releaseResolvedParks` drains them at boot from /me/context, because the live
`user-shown` / `event-opened` events only reach a tab that was open when the host acted,
and the usual sequence is the other way round.

Two signals were firing on nothing. A filtered feed set `feedStale` on EVERY delta without
deduping — and the delta cursor boundary is inclusive while sse.ts deliberately rewinds
`lastEventTime`, so deltas routinely re-return rows already delivered. With the backstop
polling every 60-120s, a guest who tapped a hashtag got a "Neue Beiträge" pill they could
never clear, each tap costing a full filtered refetch. It now dedupes in both branches.

The SSE liveness backstop had the mirror problem: `noteDelivered` harvested id, upload_id
AND user_id from every payload, so by the time anything was deleted or anyone banned, their
ids were already marked delivered from ordinary traffic about live content. The
`deleted_ids` and `hidden_user_ids` clauses were false essentially always, leaving a
half-open socket undetected while a host moderated into a feed nobody was listening to.
Each event now records only the id its own clause tests.

Also: /admin no longer bounces to /join on a cleared session — AUTH_ROUTES had the `/admin`
prefix, which suppressed clearAuth() on the dashboard and let the login guard bounce back.

b601c062bd fix(audit-2): video playback, role identity, keepsake EXIF, recover ceiling, WebKit CI
Second round: the two regressions the first round introduced, the remaining
gaps it left, and the CI change that makes the iOS guarantees actually gate a
change rather than being asserted.

Squashed from 9 commits, original messages preserved below.

──────── docs(deploy): document the update path — `up -d` alone ships nothing

The README only ever described a fresh install. There was no update section
anywhere, and `--build` appeared nowhere in the docs.

That matters because `app` and `frontend` are `build:` services with no published
image tag, and Compose has no source-change detection: if an image by that name
exists it is reused. So the natural `git pull && docker compose up -d` reports
"Container app-1 Running", rebuilds nothing, and exits 0. A deploy that shipped
none of the new code is indistinguishable from a successful one — which is how
eleven merged fixes can sit in the repo and never reach the box.

Verified both halves against a real stack rather than asserting them: with a
source change staged, `up -d` left the image ID untouched; `up -d --build`
produced a new image ID and a healthy /health.

Adds an "Updating an existing deployment" section covering backup-before-migrate,
pull, rebuild, health check, and an image-ID comparison to prove a build actually
happened. Also spells out the rollback trap: migrations run on boot and are not
undone by checking out an older commit, so rolling back code without restoring
the snapshot leaves the schema ahead of the binary and the app refusing to start.

──────── fix(video): play the actual video, and answer Range requests

Every video in the app was unplayable. Two independent defects, either one
sufficient on its own, and nothing in the suite covered either — no test
anywhere played media or asserted a `<video>` src.

1. The lightbox handed `<video>` a JPEG.

`pickMediaUrl` is mime-agnostic, and compression only ever produces a THUMBNAIL
for a video (one `ffmpeg -vframes 1` frame) — no preview, no display. So in the
DEFAULT saver mode the element's src resolved to `/api/v1/upload/{id}/thumbnail`,
served as `image/jpeg` with `nosniff` so the browser can't even sniff its way
out. Chromium reports DEMUXER_ERROR_COULD_NOT_OPEN.

Fixed in the lightbox rather than in `pickMediaUrl`: FeedListCard shares that
helper and legitimately wants the thumbnail for its `<img>` poster, so a central
mime branch would break the feed. This mirrors the rule the diashow already
applies ("videos play the original file directly"). Added `preload="none"` so
saver-mode guests on cellular still fetch nothing until they press play — there
is no smaller video derivative to offer them — plus `playsinline`, without which
iOS hijacks playback into fullscreen.

2. `stream_media_file` ignored Range entirely.

It took no request headers, so it could not see `Range`; it always returned 200
with the whole body and never sent Accept-Ranges or Content-Range. iOS Safari
opens every `<video>` with a `Range: bytes=0-1` probe and abandons the load
without a 206 — so video failed on the app's primary platform even in `original`
mode, where the src was already correct.

Adds single-range support (`bytes=N-`, `bytes=N-M`, `bytes=-S`) with 206 +
Content-Range, 416 + `bytes */len` past EOF, and Accept-Ranges advertised on
every response. Anything it won't handle — multi-range, non-bytes units, garbage
— falls back to a full 200, which RFC 9110 explicitly permits and which is safer
than guessing. All four media routes share the helper, so seeking works
uniformly.

`get_original` now serves `inline` instead of `attachment`. An attachment
disposition is hostile to a `<video>` element, and this route is the only source
of playable video bytes; it also matches what the UI promises, since the action
is labelled "Original anzeigen" — view, not download. `no-store` is deliberately
kept so a takedown still revokes access promptly; ranges work fine under it, the
client just re-fetches.

Tests: 11 unit tests pin the parser (the iOS `bytes=0-1` probe, inclusive ends,
suffix ranges, clamping past EOF, 416 vs 200, malformed fallbacks). A new
03-feed/video-playback spec asserts the src is the original and not the
thumbnail, that the browser accepts the bytes as media (readyState > 0, no
MediaError), that no video bytes are delivered before play, and that Range
returns the correct 206 slices and a 416 past EOF — verified on both Chromium
and WebKit.

The "not downloaded before play" test asserts no *delivered body* rather than no
request: WebKit opens a connection for a preload="none" video and immediately
aborts it (GET, no Range, status 0, nothing transferred) while Chromium issues
nothing at all. The portable guarantee is that no response carrying bytes
completes.

──────── fix(auth): bind the role store to the identity, not to the tab

The role store I added in the moderation work is a module-level singleton seeded
ONCE at import. `goto()` is a client-side navigation, so leaving and re-joining in
the same tab re-imports no module and re-runs no onMount — the previous user's
role simply stayed resident. Nothing reset it: not join, recover, admin login,
"Event verlassen", `clearAuth`, nor the api.ts 401 auto-clear.

So a host who left, followed by a guest joining on the same phone, left that guest
with `isStaff === true` and a "🚫 Beitrag entfernen" action on other people's
photos. The backend 403s the delete, so this was a false affordance rather than a
privilege escalation — but `/feed` never fetched `/me/context`, so unlike every
other route it never self-corrected either. It survived until a hard reload.

The mirror case was equally broken and easier to overlook: a guest who recovered
into a host account got NO host affordances.

`clearAuth` already had a hook registry for exactly this shape of problem, with a
comment explaining it exists to avoid circular imports. Add the missing mirror,
`onSetAuth`, fired by both `setAuth` and `setAdminAuth` after the new token is
resident, and have the role store register on both sides: clear to null on
logout, re-seed from the new token on login. That also gives
`syncRoleFromToken` — dead code with zero callers since I introduced it — its
intended purpose.

Seeding from the claim fixes the reported bug, but the claim is frozen for the
token's 30-day life, so a promotion or demotion still wouldn't reach the feed.
`/feed` now calls the existing `refreshEventState()` on mount, which fetches
`/me/context` and applies both the authoritative role and the lock/release state
in one request. The feed is the one route gating a destructive action on the role,
so it should not be the only route running on a stale claim.

Tests: 04-host/role-identity-reset drives the real flows. The first asserts the
host DOES see the action before asserting the newcomer does not — a negative
assertion alone would pass against a build that shipped no moderation at all. The
second covers the mirror, promoting a guest server-side while their resident token
still claims `role: guest`, so a fix that only cleared the role would fail it.

──────── fix(compression): reclaim failed originals instead of leaking them

Round 1 stopped the compression worker deleting an upload's original on failure —
a transient ENOSPC or a codec panic must never destroy the only copy of a photo a
guest cannot retake. But it left `Upload::soft_delete`'s quota refund in place, so
the bytes stayed on disk while the uploader was charged nothing for them.

That is worse than it first looks. The row is soft-deleted, so the file is
invisible and unowned; a guest hitting a reproducible codec failure can accumulate
orphans indefinitely at zero personal cost. And `active_uploaders` counts only
users with non-deleted uploads, so dropping out of that count RAISES everyone's
per-user ceiling — the leak loosens the very quota meant to contain it.

Keep the refund: the uploader didn't cause the failure and shouldn't silently lose
quota to it. Bound the leak instead, with an hourly sweep alongside the existing
session cleanup in `spawn_periodic_tasks`, reclaiming failed originals older than
14 days — comfortably longer than any single event, so an operator investigating a
failed upload still has the file.

The selection predicate is the entire safety argument, so it is deliberately
narrow: `compression_status = 'failed'` AND soft-deleted AND past the window AND
`original_path <> ''`. That is exactly the state the give-up path leaves behind,
and it cannot reach a live upload, an owner-deleted one, or a failure still inside
its recovery window. `original_path` is cleared after a successful reclaim, which
makes the sweep idempotent — otherwise a row whose file is already gone is
re-selected on every tick forever. The row itself is kept as the audit trail.

Tests reproduce the selection verbatim (same pattern as upload_concurrency) and
assert it against five near-misses that must survive, both sides of the retention
boundary, and the idempotence property.

Also fixes two comments in export.rs still claiming "the compression worker
hard-deletes an original when its transcode fails" — no longer true, and the
defensive handling they justify is now justified by this sweep and by ordinary
deletes instead.

──────── fix(export): apply EXIF orientation in the keepsake too

Round 1 fixed EXIF orientation in the compression worker, which corrected the live
app — feed preview and diashow display. The export worker was missed, and it does
not reuse those derivatives: it re-decodes the originals itself with `image::open`,
which ignores the orientation tag, then re-encodes to JPEG, which drops the tag —
so the viewer has no way to recover it.

The damage was oddly shaped, which is exactly why it reads as a viewer bug:

  Gallery.zip originals              correct  (byte-copied, EXIF intact)
  Memories viewer grid thumbnails    SIDEWAYS (always)
  Memories viewer full image >5 MB   SIDEWAYS (re-encoded at 2000px)
  Memories viewer full image ≤5 MB   correct  (streamed byte-for-byte)

So in the keepsake people actually keep, every portrait photo in the grid was on
its side, and clicking through silently "fixed" small photos but not large ones.

Rather than paste the decoder dance a third time, extract `services::imaging::
decode_oriented` and route both workers through it, so there is exactly one way to
turn a file on disk into a DynamicImage. It carries a second invariant that had
also drifted: `image::open` applies NO decode limits, so the export path was
decoding arbitrary user-supplied images unbounded — the decompression-bomb cap
existed only in the compression worker. Both now come as a pair, which is the
point of having one function.

Not done: switching export to consume the existing `display` derivative. It would
fix orientation and drop a redundant full-resolution decode per photo, but it
would also replace the pristine ≤5 MB originals in the keepsake with 2048px
re-encodes — a real quality regression in the one artefact people keep forever.

Test uploads the round-1 fixture (40x20 landscape tagged Orientation=6), runs a
real export, pulls the thumbnail out of Memories.zip and asserts it came back
portrait — with a sanity check that the source really is stored landscape, so the
test can't pass against a pipeline that does nothing.

──────── fix(recover): cap name cycling, and stop bcrypt blocking the runtime

Round 1 gave /join a per-IP ceiling and left /recover with only its
`recover:{ip}:{name}` bucket. That key is right for the job it was written for —
stopping someone who knows a display name (they're listed on the feed) from
burning the victim's 3-strike PIN counter and locking them out on repeat. But the
name is ATTACKER-CHOSEN, so cycling names mints a fresh 5-attempt bucket every
time and the per-IP cost is unbounded.

What sits behind that limiter makes it worse than a normal flood: every call runs
a cost-12 bcrypt verify, including an UNCONDITIONAL throwaway verify for names
that don't exist — added deliberately to close a timing oracle. So an unknown name
is the single cheapest way to make the server do ~200ms of hashing.

Adds `recover_ip_rate_per_min` (default 30, migration 019), checked BEFORE the
per-name bucket so a name generator can't walk past it. 30/min is far above any
real recovery attempt while capping a flood. The per-name bucket is untouched and
remains the anti-guessing control.

The second half matters as much as the first: bcrypt was running inline on the
async runtime everywhere. At cost 12 that pins a tokio worker thread for ~200ms,
and there is only one per core — so a login flood stalled every other request on
the box, including the feed. There was no spawn_blocking anywhere in the auth
module, despite SECURITY-BACKLOG claiming bcrypt had been offloaded.

Route all of it through `verify_password` / `hash_password` on the blocking pool.
That covers /recover, /admin/login, the host PIN reset, and — the one most likely
to bite at a real event — the PIN hash minted on every single /join. Saturating
the blocking pool degrades logins; saturating the worker threads degrades
everything.

Tests: cycling distinct names from one IP now hits the ceiling with a Retry-After,
and — the assertion that keeps the fix honest — repeated wrong PINs against ONE
name are still throttled with the ceiling set generously high, so the ceiling
added protection rather than replacing it.

──────── ci(e2e): run WebKit, so the iOS guarantees actually gate a PR

The workflow installed only Chromium and ran chromium-desktop + chromium-mobile.
iOS Safari is the app's stated primary user — a wedding guest opening a QR link —
and WebKit is the only engine in the matrix that reproduces two of its behaviours:

  - it enforces X-Frame-Options on the hidden download iframe, so a site-wide DENY
    makes the keepsake download silently do nothing. Blink hands attachments to
    the download manager before the frame check and never notices.
  - it abandons a <video> load unless its Range probe gets a 206.

Both of those shipped. Adding 06-export to the webkit project in the round-1 fix
bought nothing on a PR, because CI never ran that project at all — the regression
test written specifically to catch the blocker only ever executed locally.

Runs 71 tests (67 pass, 4 skip on the documented IndexedDB-blob harness
limitation) in ~1.5 minutes locally, using the exact command added here.

──────── chore(backend): satisfy cargo fmt

`checks.yml` runs `cargo fmt --check`, and it has been failing since the round-1
audit fixes: I gated those on `cargo build` and `cargo clippy` but never ran fmt,
so three files drifted then and eight more this round. Pure formatting — no
behaviour change; clippy stays at zero and all 70 backend tests still pass.

Worth noting for next time: clippy passing is not evidence fmt does.

──────── chore: satisfy prettier in frontend and e2e

`checks.yml` runs `npm run format:check` for both projects and both were failing.

- frontend/src/lib/ui-store.ts is mine, unformatted since the round-1 upload-queue
  badge fix — the same miss as the rustfmt one: I gated on svelte-check and eslint
  but never on format:check.
- e2e/loadtest/* and e2e/shots.mjs have been unformatted since 7758270 and are
  unrelated to the audit work. Fixed here because they block the same gate and the
  fix is mechanical; no behaviour change in either project.

Still red and deliberately NOT fixed here: `npm run lint` in the frontend reports
`svelte/prefer-svelte-reactivity` on routes/diashow/+page.svelte:208 (a mutable
`Set` where the rule wants `SvelteSet`), pre-existing since 5009590. That one is a
real reactivity change in code I have no test coverage for, so it belongs in its
own change rather than smuggled into a formatting commit.

f8cba95e49 chore(frontend): add ESLint + Prettier; fix real findings; format the tree
The frontend had no JS/TS linter — only svelte-check. Add flat-config ESLint (typescript-eslint
+ eslint-plugin-svelte) and Prettier (tabs/single-quote, matching the existing style).

Rules encode "catch bugs, not enforce taste":
  - svelte/require-each-key KEPT — it is the exact bug class as the feed mis-tap fix. Fixed every
    flagged block: keyed activeFilters, filteredUsers, stagedFiles (by previewUrl), captionTags,
    admin tabs/jobs/users, the export-viewer suggestions/filters/comments, and the static skeleton
    loops.
  - svelte/prefer-svelte-reactivity KEPT — inline-disabled only the verified-safe sites (a local
    freq Map in a $derived.by, throwaway URLSearchParams query builders), with a reason each.
  - svelte/no-navigation-without-resolve OFF — wants resolve() around every goto()/href; taste, not
    a bug, and pure churn.
  - svelte/no-unused-svelte-ignore OFF — those comments are consumed by svelte-check, which ESLint
    can't see, so it wrongly calls them unused; removing them would reintroduce a11y warnings.
  - no-explicit-any OFF for *.test.ts only (partial fixtures legitimately use any).

Real code fixes beyond keys: removed a dead jobLabel(), an unused ViewerComment import and unused
catch binding, an unused scroll-lock arg, and replaced an empty interface with a type alias.

Then `prettier --write` (54 files). Formatting only. Verified: eslint clean, svelte-check 0 errors,
vitest 46 passed, vite build succeeds.

811c724685 fix(audit-followup): close regressions/gaps from the persona-audit re-review
Adversarial re-review of the persona-audit commit surfaced two HIGH regressions I'd
introduced plus MED/LOW gaps. All fixed:

HIGH
- Auth privilege escalation: reads are sessionStorage-first, but guest `setAuth` wrote only
  localStorage — a resident admin token shadowed a new guest login (guest ran as admin on a
  shared device). setAuth/setAdminAuth now DISPLACE the other store so exactly one identity
  is resident. Adds unit + e2e regression guards.
- Host dashboard: `exportGenerating` used `||`, so a one-half export failure stuck on
  "wird erstellt…" forever and never showed the re-release hint. Changed to `&&`.

MEDIUM
- Locked-upload auto-resume was unreliable (`event-opened` has no reconnect replay and SSE
  is down on non-feed pages) — now also resumes on `feed-delta`, which fires on every SSE
  reconnect.
- Queue-cap eviction could drop a recoverable locked item (parked as `error` with a live
  blob) — now evicts only `done`/`blocked`.
- Host page async-`onMount` leaked SSE handlers if unmounted mid-load — added a `destroyed`
  guard before registration.

LOW
- An unparseable 403 body now keeps the blob (reversible) instead of purging it.
- `refreshEventState` is sequence-guarded so a late close-refresh can't clobber a reopen.
- `/export/status` moved out of the all-or-nothing `reload()` so its failure can't blank the
  whole host dashboard.

Verified: svelte-check 0 errors, 36 frontend unit tests (incl. new displacement guards).

36fe59caa5 fix(user-flow): persona-audit fixes — ban replay, locked-upload data loss, host UX, admin session
Follows the perf + security + user-flow work with a role/persona audit (guest, host,
admin, projector) and fixes across three review rounds. Highlights:

HIGH
- Ban now replays on reconnect. A ban isn't a soft-delete, and the `user-hidden` SSE has
  no replay, so a client that missed it (esp. the unattended diashow) kept cycling a
  banned user's slides. New `uploads_hidden_at` (migration 013) + `hidden_user_ids` in
  /feed/delta; feed + diashow evict those users. Applied even on a truncated delta.

MEDIUM
- Locked-upload data loss: a photo staged offline during a lock/release was purged as a
  terminal 4xx and lost when the host reopened. New reversible `uploads_locked` error code;
  the queue keeps the blob and auto-resumes on the `event-opened` SSE.
- Reopen after release now warns (ConfirmSheet) that it revokes the published keepsake.
- Host "forgotten-PIN" badge updates live (`pin-reset-requested` was broadcast but never
  in KNOWN_EVENTS / subscribed); host page also refetches on `pin-reset` so a two-host
  race can't hand out a conflicting PIN.
- Ban modal copy fixed (read-only ban, not "session ended"); Degradieren/Sperren/Entsperren
  hidden on peer-host rows for non-admins (they always 403'd).
- Host dashboard shows live keepsake generation progress / ready state + link to /export.
- Admin JWT moved to sessionStorage (§11.1) to bound exposure on shared devices.

Export generation guard (H1 from the prior round, hardened): per-(event,type) `release_seq`
(migration 012) with seq-guarded claim/finalize/mark_failed/update_progress, per-generation
temp/final paths, download follows `file_path`, prune only strictly-older generations.

LOW: diashow coalesces upload-processed (avoids self-rate-limit); event-closed reconciles
galleryReleased; /recover gains a forgot-PIN request + drops a stale cached PIN on 401;
delta `>=` tie-break + 429 retry; misc copy/labels.

Adds e2e: ban-replay, upload-lock-code, and rewrites export-reopen-rerelease with a
data-completeness test. Reconciles USER_JOURNEYS §9/§11.

Verified: cargo build clean, 40 unit tests, svelte-check 0 errors, 33 frontend unit
tests, 155 e2e passing on chromium-desktop.

b3d876fa85 fix(review-2): medium/low + docs — config validation, hygiene, doc sync
- compression_concurrency wired to boot config (state.rs) and removed as a
  dead admin control.
- patch_config gains per-key integer/range validation so numerically-valid-but-
  nonsensical values (-1/NaN/3.5) are rejected instead of silently reverting to
  default at read time.
- clearAuth now also clears the display name (shared-device residual).
- e2e/Caddyfile.test mirrors prod security headers + the SSE encode-exclusion so
  the test stack is representative and can catch header regressions.
- .gitignore: ignore root-level Playwright artifacts (test-results/, report).
- docs: USER_JOURNEYS §10 and SECURITY-BACKLOG updated to match the implemented
  read-only-ban behavior and the export-path fix.

309c25bc06 feat(frontend): UX review followups — primitives + a11y/UX fixes across 4 passes
New shared primitives:
- Toaster + toast-store, ConfirmSheet, Modal, focusTrap action,
  pullToRefresh action, avatarPalette + initials helper, Skeleton,
  HeartBurst, haptics, export-status store with onClearAuth hook

Critical UX/a11y:
- Replaced window.confirm with branded ConfirmSheet
- Focus management + Escape on every modal (PIN, Lightbox,
  Onboarding, ContextSheet, data-mode sheet, leave-confirm,
  HTML guide, host/admin ban + PIN-display modals)
- Sheet backdrops are real buttons with aria-label
- Silent ApiError catches now surface via global Toaster

Major polish:
- Dark-mode parity on HashtagChips + avatars (shared palette)
- Conditional Export tab in BottomNav (badge dot when ZIP ready)
- Back chevrons on /recover (history-aware) and /export
- Upload composer discard confirmation when content is staged
- Camera segmented Photo/Video shutter
- PIN auto-submit on 4th digit, paste-flash-free (controlled input)
- Welcome-back toast on /feed after PIN recovery

Minor:
- Skeleton states on feed; pull-to-refresh with live drag indicator
- Haptics on like / capture / submit / PIN-copy / onboarding complete
- Comment 500-char counter; quota "Fast voll" / "Limit erreicht" labels
- Onboarding pip ≥24px tap targets; long-press hint step
- overscroll-behavior lock on <html> while feed mounted
- teardownExportStatus wired via onClearAuth (covers 401 + explicit logout)
- ConfirmSheet per-instance titleId; Modal requires titleId or ariaLabel

Tests (7 new Playwright specs):
- 01-auth/pin-auto-submit, 01-auth/back-chevron
- 03-feed/confirm-sheet-delete, 03-feed/toast-on-failure
- 09-mobile/focus-trap, 09-mobile/sheet-escape,
  09-mobile/upload-cancel-confirm

FOLLOWUPS.md captures the deferred AT inert containment work
with acceptance criteria + implementation sketches.

251f9f1469 frontend(plumbing): shared theme tokens, cross-cutting stores, gestures, sheets
The plumbing layer the v0.16 UI features (and dark mode) build on.

Shared design tokens (Tailwind v4):
- tailwind-theme.css (new): @custom-variant dark (class-driven, beats OS
  default) + @theme color/font/radius tokens + baseline html/html.dark
  rules so any page that hasn't been re-themed still renders the right
  body bg + color-scheme.
- src/app.css + export-viewer/src/app.css now import the shared theme.
- src/app.html: 6-line FOUC guard sets <html class="dark"> before paint
  (mirrored from theme-store.ts) so dark reloads no longer flash white.
  Adds <meta name="theme-color"> kept in sync by initTheme().

Cross-cutting stores (one per concern, per docs/FEATURES §2.9):
- data-mode-store.ts: 'saver' | 'original' per-device, plus pickMediaUrl
  helper so feed cards / lightbox / diashow all resolve URLs the same way.
- privacy-note-store.ts: hydrated from /me/context, refreshed on SSE
  event-updated.
- quota-store.ts: { enabled, used, limit, active_uploaders, free_disk },
  refreshed after each upload completes.
- theme-store.ts: 'system' | 'light' | 'dark' preference + derived
  appliedTheme + initTheme() that syncs <html class>, localStorage,
  and the theme-color meta. Listens to prefers-color-scheme.
- auth.ts: currentPin writable mirror + clearPin() helper called from
  the global pin-reset SSE handler — fixes the stale-PIN bug where the
  localStorage copy survived a reset.

DTO mirror:
- types.ts: QuotaDto, MeContextDto, PinResetResponse, DeltaResponse each
  carry a `// mirrors backend/...` comment per the lib README convention.

SSE client:
- sse.ts: KNOWN_EVENTS registry (one entry per server-emitted type),
  synthetic feed-delta dispatched after foreground reconnect via the
  /feed/delta?since= endpoint, exponential backoff (1 → 60 s + jitter)
  on errors, attempt counter reset on user-initiated visibility resume.

Upload queue:
- upload-queue.ts: IDB schema bumped to v2 — entries tagged with userId;
  loadQueue filters by current user (no cross-user leak on shared
  devices); uploadItem refuses to upload an entry whose userId differs
  from getUserId() (defense-in-depth); new clearQueue() called on
  explicit logout. v2 upgrade wipes pre-v2 entries (no userId, can't
  attribute safely).

Mobile primitives:
- actions/longpress.ts: 500 ms hold with 10 px move tolerance, swallows
  the next click + the right-click contextmenu so the gesture doesn't
  double-fire the inner button's onclick.
- actions/doubletap.ts: tap-pair detector that preventDefaults the
  second tap so iOS Safari doesn't also zoom on double-tap.
- components/ContextSheet.svelte: generic bottom sheet driven by a

75d186fad3 feat: implement My Account page
Add /account route showing display name (from localStorage), role badge,
session expiry decoded from JWT, and recovery PIN display with copy button.
Join and recover flows now persist display_name to localStorage via setAuth().
Feed header logout button replaced with person-icon link to /account;
logout is available from the account page.

71a2987a3e feat: implement host dashboard
Add Host Dashboard for event and guest management, accessible at /host.

Backend — new /api/v1/host/* endpoints (RequireHost auth):
- GET  /host/event                    → event name + lock/release state
- POST /host/event/close|open         → lock or unlock uploads; SSE broadcast
- POST /host/gallery/release          → set release timestamp, enqueue export jobs
- GET  /host/users                    → all guests with upload count & bytes
- POST /host/users/{id}/ban           → ban with optional upload-hide choice
- POST /host/users/{id}/unban         → lift ban
- PATCH /host/users/{id}/role         → promote guest→host or demote host→guest
- DELETE /host/upload/{id}            → host-level soft-delete + SSE
- DELETE /host/comment/{id}           → host-level soft-delete

Frontend — /host page:
- Event controls: lock/unlock toggle and release-gallery button with status badges
- Guest table: display name, role badge, upload count, storage used
- Ban flow: modal asking whether to keep or hide the user's uploads
- Promote/demote buttons respecting caller role (host can promote guests; admin can demote hosts)
- auth.ts: getRole() decodes JWT payload client-side to gate the route
