- /images/recent, /images/all and /images/output parse limit/offset
through parse_page_params on every path (absent, 0, negative, float
strings), and the clamped values are what reach the DB. /images/all
gets its own MAX_BULK_LIMIT ceiling instead of an unbounded query;
/images/recent caps its fetch window at MAX_RECENT_IMAGES_WINDOW.
- parse_page_params also clamps offset to MAX_PAGE_OFFSET so values past
int64 no longer surface as a 500 from SQLite.
- Gallery and thumbnail scans share _iter_media_files: no symlink
following, MAX_SCAN_DEPTH, and MAX_GALLERY_FILES / MAX_THUMBNAIL_FILES
caps. Thumbnail size comes only from named presets.
- JSON bodies on /images/link and /images/generate-thumbnails are read
in bounded chunks; over MAX_JSON_BODY_BYTES answers 413, malformed or
non-object JSON answers 400.
- /images/link only accepts media paths inside the allowed directories
(403 otherwise), closing a path-existence oracle.
