+# Mobile Testing Guide — EventSnap v0.15.0
+
+## Setup
+
+### Dev Servers
+
+| Service | URL | Notes |
+|---------|-----|-------|
+| Frontend | `http://localhost:5173` | Vite dev server, hot-reload |
+| Backend API | `http://localhost:3000` | Rust/Axum |
+| Database | `localhost:5432` | PostgreSQL (Docker) |
+
+The frontend dev server proxies `/api` and `/media` to the backend automatically.
+
+**Mobile device access:** Connect your phone to the same Wi-Fi network.
+Find your machine's local IP (`ip a | grep 192.168` or `hostname -I`), then open
+`http://<your-ip>:5173` on your phone.
+
+### Browser DevTools Mobile Emulation (quick testing without a phone)
+
+1. Open Chrome → DevTools (`F12`) → Toggle device toolbar (`Ctrl+Shift+M`)
+2. Select **iPhone 14 Pro** or **Pixel 7** from the device dropdown
+3. Reload the page — safe-area insets and viewport are emulated
+4. To test touch gestures: enable "Touch" in the three-dot menu inside the device toolbar
+
+---
+
+## Test Accounts
+
+Use the following to get all three roles:
+
+| Role | How to get it |
+|------|--------------|
+| Guest | Join at `/join` with any name |
+| Host | Promote a guest via Host Dashboard, or set role in DB |
+| Admin | POST to `/api/v1/admin/login` or navigate to `/admin/login` |
+
+Admin password: `admin123` (set in `.env`)
+
+---
+
+## Section 1 — Bottom Navigation Bar
+
+**Goal:** Verify the tab bar is present, thumb-accessible, and correct per role.
+
+### 1.1 Bar Presence & Safe Area
+- [ ] Open `/feed` — a bottom tab bar with **Galerie**, a blue circle FAB, and **Konto** appears
+- [ ] On a real iPhone/Safari: the bar does **not** overlap the home indicator (safe-area padding)
+- [ ] On Chrome DevTools with an iPhone device: the bar is above the viewport bottom
+- [ ] Scroll down on a long feed — the bar stays **fixed** at the bottom at all times
+- [ ] The bar has a frosted-glass blur effect (`bg-white/90 backdrop-blur-md`)
+
+### 1.2 Active Tab Indicator
+- [ ] On `/feed` — the Galerie icon is **blue**; Konto icon is gray
+- [ ] Tap **Konto** — navigates to `/account`; Konto icon turns blue, Galerie goes gray
+- [ ] Tap **Galerie** — navigates back to `/feed`
+
+### 1.3 Role Gating
+- [ ] Log in as a **guest** — bar shows Galerie · FAB · Konto (3 items)
+- [ ] Log in as a **host** — same 3 items (dashboard links are inside Account, not the bar)
+- [ ] Log in as **admin** — same 3 items
+
+### 1.4 Auth Pages Hide the Bar
+- [ ] Visit `/join` — **no** bottom bar
+- [ ] Visit `/recover` — **no** bottom bar
+- [ ] Visit `/admin/login` — **no** bottom bar
+
+---
+
+## Section 2 — Upload FAB & Bottom Sheet
+
+**Goal:** Verify the FAB opens the upload sheet and both source options work.
+
+### 2.1 FAB Appearance
+- [ ] The FAB is a blue circle elevated ~12 px above the tab bar
+- [ ] A camera icon with an implicit "+" meaning is shown
+- [ ] When uploads are in the queue (pending or uploading), a **red badge number** appears on the FAB
+
+### 2.2 Sheet Opens & Closes
+- [ ] Tap the FAB — a bottom sheet slides up smoothly (~300 ms) from below
+- [ ] Sheet shows: **Galerie** (blue icon), **Kamera** (purple icon), **Abbrechen**
+- [ ] Tap the gray backdrop — sheet slides **back down** and closes
+- [ ] Tap **Abbrechen** — sheet closes
+- [ ] Swipe the drag handle downward — sheet closes *(if touch gestures are enabled)*
+
+### 2.3 Gallery Source
+- [ ] Tap **Galerie** — the native file picker opens
+- [ ] Select 1–3 images or videos
+- [ ] Sheet closes; you are navigated to `/upload` (the composer page)
+- [ ] Thumbnail strip at the top shows your selected files
+- [ ] **Bottom nav is gone** on this page (immersive full-screen)
+
+### 2.4 Camera Source
+- [ ] Tap the FAB → **Kamera**
+- [ ] Browser asks for camera permission — grant it
+- [ ] Full-screen camera UI appears (existing CameraCapture component)
+- [ ] Take a photo
+- [ ] Camera closes; you are navigated to `/upload` with the captured image in the strip
+
+### 2.5 Upload Composer Page
+- [ ] Back `×` button top-left → returns to `/feed`, clears pending files
+- [ ] Thumbnail strip scrolls horizontally when >3 files
+- [ ] Each thumbnail has a small `×` to remove it — tapping removes that file only
+- [ ] Caption `<textarea>` is **auto-focused** (keyboard opens on mobile)
+- [ ] Type `#party #spaß` in the caption — **quick-tag chips** appear below the textarea in real time
+- [ ] Quick-tag chips are read-only (they reflect what's already in the caption)
+- [ ] The **"Hochladen"** sticky button at the bottom shows the file count: "2 Dateien hochladen"
+- [ ] Button is **disabled** when the strip is empty
+- [ ] Also a smaller "Hochladen" button in the header (convenient on desktop/landscape)
+- [ ] Tap **Hochladen** — files are queued, you are returned to `/feed`
+- [ ] A **slim blue progress bar** appears just above the bottom tab bar while uploading
+- [ ] FAB shows a **red badge** during upload; badge disappears when done
+- [ ] A brief "Fertig" / completed state appears in the UploadQueue (check queue store)
+
+---
+
+## Section 3 — Feed: List View
+
+**Goal:** Verify the default chronological list view.
+
+### 3.1 Default State
+- [ ] Open `/feed` — **list view** is active by default (≡ icon highlighted in the toggle)
+- [ ] Posts appear as full-width cards in reverse-chronological order (newest first)
+
+### 3.2 List Card Anatomy
+For each card, verify:
+- [ ] **Avatar circle** with the uploader's initial letter and a deterministic color
+- [ ] **Display name** + **relative timestamp** ("vor 2 Min.", "vor 1 Std.", etc.)
+- [ ] **Media**: full-width image, or video with a play button overlay
+- [ ] **Caption** below the media (truncated to 3 lines with `...` if long)
+- [ ] **Like count** (❤️) and **Comment count** (💬) action buttons
+- [ ] Tapping the ❤️ toggles the like optimistically (count changes immediately)
+- [ ] Tapping 💬 or the media opens the **Lightbox Modal** (existing behavior, unchanged)
+
+### 3.3 Hashtag Chips (List View Only)
+- [ ] Below the main header, hashtag filter chips are visible in **list view**
+- [ ] Tap a hashtag chip — feed re-fetches filtered by that tag
+- [ ] Tap **Alle** — returns to unfiltered feed
+- [ ] Chips are **not visible** when grid view is active
+
+### 3.4 Infinite Scroll
+- [ ] Scroll to the bottom — more posts load automatically
+- [ ] A spinner appears briefly while loading more
+- [ ] Scroll sentinel triggers ~200 px before the actual bottom
+
+### 3.5 Real-Time Updates (SSE)
+- [ ] Open the feed on two devices/tabs simultaneously
+- [ ] Upload a photo on one — it appears at the **top** of the other's list view in real time
+- [ ] Like a post on one — the count updates on the other
+
+---
+
+## Section 4 — Feed: Grid View & Search
+
+**Goal:** Verify the 3-column grid, search bar, autocomplete, and filter chips.
+
+### 4.1 Switching to Grid View
+- [ ] Tap the ⊞ grid icon in the header — view switches to a 3-column grid
+- [ ] The ≡/⊞ toggle shows ⊞ as active (white background, shadow)
+- [ ] Hashtag chips **disappear**; a **search bar** slides in below the header
+
+### 4.2 Grid Layout
+- [ ] Grid is **3 columns** with equal square cells (no 2-column fallback on mobile)
+- [ ] Videos show a ▶ play button overlay
+- [ ] Tapping a cell opens the Lightbox Modal
+- [ ] Grid background is seamless (0.5px gap between cells)
+
+### 4.3 Search Bar
+- [ ] Search bar shows: 🔍 icon, placeholder "Nutzer oder #Tag suchen…", × clear button
+- [ ] Tapping the bar focuses it and opens the keyboard
+- [ ] × button appears only when there is text in the input; tapping it clears the query
+
+### 4.4 Autocomplete — On Focus (Empty)
+- [ ] Focus the search bar with no text — a dropdown appears with:
+  - Up to 3 uploader names (person icon)
+  - Up to 3 popular tags (#)
+- [ ] The dropdown disappears when the input loses focus (150 ms delay)
+
+### 4.5 Autocomplete — Tag Suggestions
+- [ ] Type `#` — only **tag suggestions** appear (no users), sorted by frequency
+- [ ] Type `#par` — only tags starting with "par" remain (e.g. `#party`, `#parade`)
+- [ ] Tap a suggestion — it's added as a **blue filter chip** below the search bar; input clears
+
+### 4.6 Autocomplete — User Suggestions
+- [ ] Type a partial name (e.g. `max`) — users matching "max" appear first, then tags containing "max"
+- [ ] Tap a user suggestion — chip added: shows the name without `#` prefix
+
+### 4.7 Filter Chips
+- [ ] After selecting a tag filter — grid shows only posts with that tag in the caption
+- [ ] Select a second tag — grid shows posts with **either** tag (OR logic)
+- [ ] Select a user **and** a tag — grid shows posts by that user **that also** have that tag (AND across types)
+- [ ] Each chip has an **× remove button**; tapping it removes only that chip
+- [ ] When 2+ chips are active: **"Alle löschen"** link appears; tapping clears all filters
+- [ ] When no results match: "Keine Treffer für die gewählten Filter." + "Filter zurücksetzen" button
+
+### 4.8 Switching Back to List View
+- [ ] Tap ≡ — list view returns; search bar gone; hashtag chips reappear
+- [ ] Active grid filters are **reset** when switching back to list (no stale state)
+
+---
+
+## Section 5 — Account Page
+
+**Goal:** Verify the profile card, dashboard links, and leave-confirm flow.
+
+### 5.1 Profile Card
+- [ ] Open `/account` via the Konto tab
+- [ ] **Avatar circle** shows your initial letter in a deterministic color
+- [ ] **Display name** and **role badge** (Gast / Gastgeber / Admin) shown
+- [ ] Session expiry date shown in small text below
+
+### 5.2 Dashboard Links (Host/Admin Only)
+- [ ] Log in as a **guest** — no "Dashboards" section visible at all
+- [ ] Log in as a **host** — "Dashboards" section shows ⭐ **Host-Dashboard** → chevron
+  - [ ] Tapping it navigates to `/host`
+  - [ ] No Admin-Dashboard link visible
+- [ ] Log in as **admin** — both links appear:
+  - [ ] ⭐ Host-Dashboard → `/host`
+  - [ ] 🛡 Admin-Dashboard → `/admin`
+
+### 5.3 PIN Card
+- [ ] Amber card shows the 4-digit PIN in large monospace font
+- [ ] **Kopieren** button copies to clipboard; label changes to "Kopiert!" for 2 seconds
+- [ ] If no PIN is stored: fallback message shown
+
+### 5.4 Konto Section
+- [ ] **Gerät wechseln / PIN nutzen** → navigates to `/recover`
+- [ ] **Event verlassen** (red text) → tapping opens a **leave-confirm bottom sheet**
+  - [ ] Sheet shows: "Event verlassen?", "Du wirst abgemeldet…", red "Abmelden" + "Abbrechen"
+  - [ ] Tap backdrop — sheet closes, you remain logged in
+  - [ ] Tap **Abbrechen** — same
+  - [ ] Tap **Abmelden** — you are logged out and redirected to `/join`
+
+### 5.5 No Stale Nav Links
+- [ ] **No** "Zur Galerie" link in the header (navigation is via the bottom bar)
+
+---
+
+## Section 6 — Host Dashboard
+
+**Goal:** Verify the back arrow, collapsible sections, and all existing host actions still work.
+
+### 6.1 Navigation
+- [ ] Open Host Dashboard via Account → ⭐ Host-Dashboard
+- [ ] Page shows a **← back arrow** in the top-left header
+- [ ] Tapping it navigates to `/account`
+- [ ] **No** shield/gallery header icons (removed)
+- [ ] Bottom tab bar is still visible
+
+### 6.2 Statistiken Section (Collapsible)
+- [ ] Section is **expanded** by default with a downward chevron
+- [ ] Shows a 2×2 grid of stat cards: Gäste, Uploads, Uploads status (Offen/Gesperrt), Freigegeben (Ja/Nein)
+- [ ] Numbers are large and readable on mobile
+- [ ] Tap the **Statistiken** header button — section collapses (smooth max-height animation)
+- [ ] Chevron rotates 180° to point upward when collapsed
+- [ ] Tap again — section expands
+
+### 6.3 Event-Einstellungen Section (Collapsible)
+- [ ] Collapse/expand works same as above
+- [ ] Shows **"Uploads sperren"** (amber) / **"Uploads wieder öffnen"** (green) button
+- [ ] Shows **"Galerie freigeben"** (blue) / "Galerie bereits freigegeben" (disabled gray)
+- [ ] Tap "Uploads sperren" — toast confirms, button switches to "Uploads wieder öffnen"
+- [ ] Existing functionality unchanged
+
+### 6.4 Nutzerverwaltung Section (Collapsible)
+- [ ] **Search bar** at top of section filters the user list in real time (client-side)
+- [ ] Each user row shows name, role badge, banned badge (if applicable), upload count/bytes
+- [ ] **Sperren** button triggers the existing ban modal (confirm + hide-uploads checkbox)
+- [ ] **Entsperren** appears for banned users
+- [ ] **Host** button promotes a guest to host role
+- [ ] **Degradieren** appears for hosts (admin only)
+- [ ] Toast notifications appear above the bottom bar (not obscured by it)
+
+---
+
+## Section 7 — Admin Dashboard
+
+**Goal:** Verify the inner tab bar, all 4 tabs, and the new Nutzer tab.
+
+### 7.1 Navigation
+- [ ] Open Admin Dashboard via Account → 🛡 Admin-Dashboard
+- [ ] Page shows **← back arrow** → `/account`
+- [ ] **No** star/gallery header icons
+- [ ] Bottom tab bar visible
+
+### 7.2 Inner Tab Bar
+- [ ] A second tab bar appears **below the main header**, sticky on scroll
+- [ ] 4 tabs: **Stats · Config · Export · Nutzer**
+- [ ] Active tab has a blue bottom border and blue text
+- [ ] Inactive tabs are gray
+- [ ] Tabs are scrollable horizontally (try narrowing viewport)
+- [ ] Switching tabs is instant with no page reload
+
+### 7.3 Stats Tab
+- [ ] Shows a **2×2 grid** of metric cards: Gäste, Uploads, Kommentare, Speicher %
+- [ ] Values are large (`text-3xl`)
+- [ ] Below the grid: a full-width disk usage bar with color coding
+  - Blue ≤ 74%, Amber 75–89%, Red ≥ 90%
+- [ ] Exact used/total/free values shown
+
+### 7.4 Config Tab
+- [ ] Shows stacked label + full-width input for each of the 8 config keys
+- [ ] Inputs are `type="number"` with large touch targets
+- [ ] A **"Speichern"** button is **sticky at the bottom** of the tab (always visible, even on long scroll)
+- [ ] Edit a value → tap Speichern → toast "Konfiguration gespeichert."
+- [ ] Tap Speichern with no changes → toast "Keine Änderungen."
+
+### 7.5 Export Tab
+- [ ] **"Galerie freigeben"** button triggers gallery release
+- [ ] **"Aktualisieren"** button refreshes the jobs list only (no full page flash)
+- [ ] Export jobs listed with status chips: Ausstehend (gray) / Läuft (blue) / Fertig (green) / Fehlgeschlagen (red)
+- [ ] Running jobs show a progress bar
+- [ ] Failed jobs show the error message in red
+
+### 7.6 Nutzer Tab (New)
+- [ ] Users are loaded from `/host/users` (admin shares host permissions)
+- [ ] **Search bar** filters list in real time
+- [ ] Same ban/unban/promote/demote actions as Host dashboard
+- [ ] After an action (e.g. ban) only the users list refreshes, not the whole page
+
+---
+
+## Section 8 — Toast Position
+
+- [ ] On host/admin pages, toasts appear at `bottom-24` (above the bottom nav bar)
+- [ ] Toasts are **not** obscured by the nav bar
+
+---
+
+## Section 9 — Desktop Usability (Second Citizen)
+
+**Goal:** Confirm all pages are still usable on a wide viewport.
+
+### 9.1 Layout Centering
+- [ ] On a 1280px+ viewport, all pages center their content at `max-w-2xl` or `max-w-3xl`
+- [ ] Bottom tab bar spans full width but content columns remain centered
+- [ ] No content is clipped or overflows horizontally
+
+### 9.2 Feed Desktop
+- [ ] List view: cards are centered, readable at 672px max width
+- [ ] Grid view: 3 columns at max-width — cells are larger and look good
+- [ ] Search bar is full-width within the max-width container
+
+### 9.3 Upload Composer Desktop
+- [ ] Upload page is full-height, centered column
+- [ ] Both the header "Hochladen" button AND the sticky bottom button are present
+- [ ] Desktop users can click the header button (more convenient without reaching to bottom)
+
+### 9.4 Host / Admin Desktop
+- [ ] Host collapsible sections work with mouse clicks
+- [ ] Admin inner tabs work with mouse clicks; all 4 tabs visible without scrolling at 1280px
+- [ ] Config tab sticky save is visible on desktop scroll
+
+---
+
+## Section 10 — Edge Cases
+
+### 10.1 Upload with No Files Selected
+- [ ] Navigate directly to `/upload` in the browser
+- [ ] No files pending → "Keine Dateien ausgewählt" screen shown with "Zurück" button
+- [ ] "Hochladen" button is disabled
+
+### 10.2 Rate Limiting
+- [ ] Upload rapidly beyond the configured limit (default: 10/hour)
+- [ ] A `429` response is received
+- [ ] The countdown banner appears above the bottom nav: "Upload-Limit erreicht. Wird in X Sek. automatisch fortgesetzt."
+- [ ] After the countdown, the queue resumes automatically
+
+### 10.3 SSE Reconnect
+- [ ] Stop the backend briefly and restart
+- [ ] The feed reconnects (SSE) — new uploads appear once the backend is back
+
+### 10.4 Back Navigation from Upload
+- [ ] Pick files → navigate to `/upload`
+- [ ] Tap `×` → files are discarded (`clearPending()` runs, object URLs are revoked)
+- [ ] Navigate back to `/upload` directly — "Keine Dateien ausgewählt" shown (not stale files)
+
+### 10.5 Grid Filter Persistence
+- [ ] Set a filter chip in grid view
+- [ ] Switch to list view — filter is cleared (list always shows full unfiltered feed)
+- [ ] Switch back to grid — search bar is empty, no stale chips
+
+---
+
+## Known Limitations (Not Bugs)
+
+| Item | Status |
+|------|--------|
+| "Anzeigename ändern" in Account | Deferred — shown as disabled; requires `/me` PATCH endpoint |
+| Upload count in Account profile card | Deferred — requires `/me` GET endpoint |
+| CSS collapse animation on host sections | Uses `max-h` trick; may be slightly sluggish for very large user lists |
+| Autocomplete results | Derived from currently-loaded posts only; new posts via SSE update the pool automatically |
