The `metadata` JSON part in the manga-create and chapter-upload handlers was
read with `Field::bytes()`, buffering the whole part before any check — a client
could send a multi-hundred-MB metadata blob (up to the 200 MiB request limit) as
one allocation. Image parts were already streamed with a cap; metadata was the
last unbounded read.
Cap it at a shared upload::MAX_METADATA_BYTES (64 KiB) via the read_capped
streaming loop (413 on overflow), and remove the now-unused read_field_bytes
helper so the unbounded path can't return.
Tests: manga + chapter oversized-metadata parts are rejected with 413.

The cover multipart path called Field::bytes(), buffering the entire field
into memory before parse_image checked max_file_bytes — an oversized cover
was fully allocated before rejection. Add read_capped/push_capped, which
reject with 413 as soon as the running total exceeds the cap (the offending
chunk is never copied in), and route both cover handlers and stage_image_part
through it.

The chapter upload handler read every `page` part fully into a Vec before
writing any, so peak memory was the whole chapter (bounded only by the
200 MiB body limit and amplified by concurrent uploads). It also accepted
an unbounded number of pages.
Stream each page part to a `staging/{upload_id}/…` key as it arrives — at
most one page's bytes are held at a time — then, once the chapter row (and
its id) exists, promote each staged blob to its final key via a new
`Storage::rename` (LocalStorage: fs rename; default impl: stream+delete for
future backends). Finalization is all-or-nothing: on any failure the DB
rolls back and both staged and already-finalized blobs are cleaned up.
Add MAX_PAGES_PER_CHAPTER (UploadConfig, default 2000, 0 = disabled),
rejecting an over-cap upload with 413 before any DB write. Also document
the crawler-side CRAWLER_MAX_IMAGES_PER_CHAPTER (added earlier) in
.env.example + docker-compose so the env-coverage test passes.
Tests: LocalStorage rename unit tests; a 413 over-cap upload test; existing
rollback + happy-path upload tests still green (the fault-injecting storage
counts put/put_stream, so mid-upload failure still rolls back).

Four small follow-ups from the 0.9.0 audit, none of them
user-visible:
- Migration 0007 drops `chapters_manga_idx`. The 0001 schema declared
both `UNIQUE (manga_id, number)` and `CREATE INDEX chapters_manga_idx
ON (manga_id, number)`, but Postgres maintains an identical index
for the unique constraint automatically — the explicit one was just
paying for a second per-write update. Query plans are unchanged
because the planner already preferred the constraint's index.
- `upload::parse_image` sniffs from the first 64 bytes instead of the
full image buffer. `infer` only looks at magic bytes anyway, so
scanning 20 MiB is wasted work. Functionally identical; cheaper in
the hot path.
- AVIF was on the whitelist but had no test fixture. New `avif_bytes`
helper produces a minimal `ftyp avif` header that `infer` recognises,
and a new `accepts_avif` unit test covers the path end-to-end.
- Frontend `request()` sets `credentials: 'include'`. Same-origin
callers see no change (default was already `'same-origin'`), but the
first user who configures `CORS_ALLOWED_ORIGINS` for a cross-origin
deployment gets working cookies without having to chase a runtime
ApiError trail.
No version bump.

POST /api/v1/mangas and POST /api/v1/mangas/{id}/chapters now accept
multipart/form-data, gated by CurrentUser:
- /mangas: required `metadata` part (NewManga JSON) + optional `cover`
image part.
- /mangas/{id}/chapters: required `metadata` (NewChapter JSON) + one or
more `page` parts ordered by arrival. Returns 404 if the parent manga
doesn't exist, 409 on duplicate (manga_id, number).
MIME is sniffed via the `infer` crate (magic bytes), not the
client-supplied filename or Content-Type. Whitelist:
jpeg / png / webp / gif / avif. Anything else → 415
unsupported_media_type. The stored key's extension is derived from the
sniffed type so a "page1.png" that's actually a JPEG lands as `.jpg`.
Size cap is two-layer:
- Request body cap (config.max_request_bytes, default 200 MiB) enforced
by axum's DefaultBodyLimit before the handler sees the request.
- Per-image-part cap (config.max_file_bytes, default 20 MiB) enforced
after reading the part, so a single oversized image can't pass even
if the total request fits.
Storage keys follow the layout documented in CLAUDE.md:
- mangas/{manga_id}/cover.{ext}
- mangas/{manga_id}/chapters/{chapter_id}/pages/{nnnn}.{ext} (1-indexed).
AppError grows PayloadTooLarge/UnsupportedMediaType/ValidationFailed
(413 / 415 / 422). ValidationFailed carries a `details` JSON object the
client can use to highlight bad fields (e.g. {"title":"required"}).
Top-level matching in code() stays exhaustive.
Backend coverage in tests/api_uploads.rs (10 cases):
- create_manga_with_cover_stores_image — file is reachable via
/api/v1/files/{key} with the right Content-Type.
- create_manga_without_cover_leaves_path_null.
- create_manga_rejects_non_image_cover_with_415 — PDF claimed as png.
- create_manga_rejects_oversized_cover_with_413.
- create_chapter_with_pages_stores_each — extension derived from
sniffed MIME, files reachable in arrival order.
- create_chapter_rejects_when_no_pages_with_422 — details.page set.
- create_chapter_rejects_renamed_non_image_page → 415.
- create_chapter_returns_409_on_duplicate_number.
- create_chapter_requires_authentication → 401.
- create_chapter_under_unknown_manga_is_404.
Existing tests/api_mangas.rs is migrated to multipart; the create
response is now 201 Created. tests/common::MultipartBuilder builds the
body by hand so the test crate stays free of HTTP-client deps.
Frontend lib/api/mangas.ts: createManga now sends FormData (metadata +
optional cover Blob). Browser fills in the boundary header automatically.
Vitest asserts the FormData structure via FileReader (jsdom doesn't
implement Blob.text()).
E2E tests wait for the post-hydration nav-login link before
interacting with the login form, fixing a flake where pre-hydration
clicks would submit via the browser default and bypass our handler.
Lockstep version bump to 0.5.0.
