DECORATION_CDN moves from Nextcloud's public DAV (a PHP session and four
cookies per image, no cache headers) to https://chat.lotusguild.org/decorations,
static files from the versioned avatar-decorations package with a one-week
cache. Pin @lotusguild/element-call-embedded 0.25.0-lotus.26, whose call
tiles accept the new origin.

Decoration preference is stored in the public Matrix profile field `io.lotus.avatar_decoration` (a slug string, e.g. `lotus_flower`). Any Lotus Chat user viewing your profile sees your current decoration.
**CDN:**
Files are self-hosted on the Lotus Nextcloud instance. Direct access: `https://drive.lotusguild.org/public.php/dav/files/{token}/cinny-decorations/{slug}.png`. `<img>` elements load cross-origin freely — no CORS headers needed.
Static files at `https://chat.lotusguild.org/decorations/{slug}.png` (thumbnails: `thumbs/{slug}.webp`), cached for a week. They come from the versioned `avatar-decorations` package in Gitea's package registry, installed by the matrix repo's LXC 106 deploy (see its README, "Avatar decorations"). To add or replace decorations, publish a new package version there, then update the catalog in `avatarDecorations.ts`. They used to be served from Nextcloud (matrix #22). `<img>` elements load cross-origin freely, so no CORS headers are needed.
**Module-level cache with in-flight deduplication:**
`useAvatarDecoration(userId)` fetches the profile field once per user per session. A `Map<userId, slug|null>` cache prevents redundant requests; a second `pending` waiters map ensures multiple components requesting the same userId simultaneously share one HTTP request rather than firing duplicates.
