User-owned named lists of mangas with an add-to-collection modal on the manga page and dedicated /collections and /collections/:id pages. - Schema (0010): `collections` (per-user case-insensitive name uniqueness) + `collection_mangas` join with cascade FKs. - Endpoints: full CRUD on `/v1/collections`, idempotent add/remove for `/v1/collections/:id/mangas`, and `/v1/mangas/:id/my-collections` for the modal's pre-checked state. Owner-mismatch surfaces as 404 (not 403) so the API doesn't disclose collection existence to non-owners; the frontend funnels 401 to /login. Three-state PATCH via a new shared `domain::patch::Patch<T>` lets clients distinguish "leave alone", "clear", and "set" for description. - Frontend: reusable `Modal` component (focus trap, opt-in backdrop close, ESC) and `AddToCollectionModal` with optimistic toggling that's race-safe under fast clicks. /collections page renders cover-collage cards; /collections/:id is editable with per-card remove. Top nav gets a Collections link. 155 backend tests (incl. 21 collection tests covering ownership, idempotence, sample-cover enrichment, three-state PATCH, FK race); 88 frontend tests; svelte-check clean.
