Backend:
- POST /api/files/lookup/ reports which MD5s are already in the library
Frontend:
- e621 client extended with post/tag/favorite types and helpers: post
search, post detail, batch posts by id, tag autocomplete, toggle
favorite
- /online: tag search with autocomplete, post grid with rating colors
and in-library badges, numbered pagination, page tag cloud, blacklist
panel and filtered counts from /users/me.json, anonymous hint
- /online/view/🆔 media viewer (sample or original, video support),
taxonomy-colored tags by category, specs sheet, favorite/unfavorite,
description, sources, pools and parent/children thumbnails
- Shared CollapsibleSidebar extracted from the library page; Online
added to the nav, command palette and sidebar toggle
Backend:
- User model gains e621_username / e621_api_key / e621_base_url
- GET/PUT /api/auth/e621/ for the owner's credentials; /me exposes only
the username and a configured flag, never the key
Frontend:
- e621 client core: Basic auth, _client param (browsers cannot set a
User-Agent), serialized queue throttled to 1 request/second, readable
error mapping
- Account screen (/account): username, API key with reveal toggle,
base URL (e621 / e926 / custom), Save + Test connection
- Credentials are fetched from the backend and held in memory only,
cleared on logout
