/**
|
||
* UpdateBackgroundModal — swap or remove the image behind a post card.
|
||
*
|
||
* Two actions:
|
||
* • Upload Image — pick a file → signed-URL upload → PUT to BFF
|
||
* → returns the refreshed post.
|
||
* • Remove Background — PUT empty image set → post falls back to the
|
||
* palette-aware quote-card gradient.
|
||
*
|
||
* Renders as a centred modal on desktop and a bottom drawer on mobile,
|
||
* mirroring the pattern used by AuthModal / ConfirmModal so the UX stays
|
||
* consistent across the app.
