Match the Figma 4206-6509 card layout for /browse: every bubble now
renders a bottom row with the publish timestamp on the left and the
action buttons on the right. Image, album, video, text and link cards
show only the FavoriteButton; file-document cards show the
FavoriteButton plus a new BubbleAttachmentDownloadButton sized to
match. Removes the absolute-positioned favorite from the default
variant, drops the right-aligned timestamp block, and strips the inline
per-row download button from FileDocBubble's default variant since the
download now lives in the footer. The 'latest' masonry variant is
untouched so the home page continues to use LatestFileCard's existing
internal footer.
The defensive rAF + scroll loop and its touching guard were added to
fight an iOS sticky-relayout quirk, but the module-level lastScrollLeft
plus the useLayoutEffect mount restore already cover the common case.
The watch loop also interfered with a fresh slide gesture immediately
after a filter tap. Strip it out together with the surrounding inline
comments so the component is the minimum needed: gold active state on
click and a remount-surviving scroll position.
Image, album, and video bubbles in the official-assets category now
render the attachment filename as a bottom-left overlay so editors can
identify the source asset at a glance. Shared AttachmentFilenameLabel
component mirrors the AttachmentDownloadPill style, uses
filenameWithExtension so MIME-only attachments still get a sensible
label, and is pointer-events-none so it never blocks the bubble's tap
target.
PublicLayout wraps the routed page in <AnimatePresence> keyed by
pathname+search, so changing ?type=… fully unmounts the page and creates
a fresh FilterChips. A useRef-based save/restore therefore reset on
every filter switch. Persist the scrollLeft in a module-level value
that survives the unmount, restore synchronously on mount, and keep an
~1.5s post-mount watch window for the iOS Safari sticky relayout that
asynchronously snaps scrollLeft back to 0. Also gate the inactive-chip
hover color behind [@media(hover:hover)] so iOS sticky-hover no longer
leaves a faint gold tint on the last-tapped filter.
Both routes render the same MessageStream; the layout wrapper used to inset
/category by px-4 / sm:px-6 on mobile while /browse stayed edge-to-edge,
shrinking bubble width and making the category waterfall feel narrower
than the all-resources page.
