Docker Build and Publish / build-and-push (push) Failing after 10s
feat: mobile opens posts as a scrolling feed instead of a modal
Tapping a post on a phone now opens a real feed page — header, media, actions,
caption, next post peeking in below — scrolled with the browser's own vertical
scrolling rather than swipe gestures. Desktop keeps the modal, where a centred
sheet with side arrows suits a pointer.

Only a window of posts is mounted: a profile here holds up to 1129 posts and
mounting them all would mean as many full-size images. The window grows in both
directions as you scroll. Growing upwards shifts everything below it, so the
scroll offset is corrected in the same frame, before paint — measured against
the real archive, an anchored post moves exactly one screen per scroll with no
jump.

Only the post crossing the viewport centre plays its video; the rest stay
paused, so a feed of reels doesn't play ten at once. The URL tracks that same
post, so scrolling updates /<archive>/p/<shortcode>/ the way Instagram does,
and the back button returns to the grid with its scroll position intact.

Feed video sizes to the container width rather than its intrinsic size: a
<video> reports 300x150 until metadata loads, which made it render narrow and
then jump to full width. It also gets a taller height ceiling than the modal so
ordinary portrait media fills the width instead of sitting in side bars.

The carousel is extracted into a shared MediaCarousel used by both surfaces, so
horizontal paging behaves identically; touch-action keeps vertical scrolling
passing through to the feed. PostModal loses its now-dead mobile swipe branch.
