* OG card for a public collection (`/c/<id>`).
|

*
|
||||
* Renders a 1200×630 image with the collection title as the centrepiece,
|
||||
* an item-count line, and the cover image dimmed behind it when present
|
||||
* (flat cream otherwise). Matches the post/profile card aesthetic.
|
||||
*
|
||||
* Data comes from the public BFF collection endpoint. The server fetch is
|
||||
* unauthenticated, so private collections return 403 → we 404 here (a
|
||||
* private collection never unfurls, which is the correct privacy stance).
