#6 Emoji were slow because Twemoji swapped EVERY emoji for an <img> fetched individually
from a CDN — opening the picker fired hundreds of image requests. Now uses the OS's own
colour emoji font: instant, zero network. twemojify() kept as a no-op.
#4 Message hover row reworked: three one-tap reactions (Like/Laugh/Surprised) + the emoji
picker + (own) Edit. Reply / Forward / Copy / Delete moved behind a ⋮ menu. Added Copy.
The row now sits FULLY above the bubble (was top:-14px, overlapping the first text line).
#9 Phone numbers linkify to tel: — mobile gets the OS "call this number?" prompt; desktop has
no dialer so it offers to copy. Regex kept conservative (10–15 digits, needs +/grouping) so
it won't grab amounts, dates or 6-digit meeting codes.
#3 Image preview zooms: wheel + pinch + double-click + ± buttons, drag to pan, keys (+/-/0),
cursor-anchored. Arrows hide while zoomed so panning isn't hijacked.
#8 Upload progress: fetch() can't report upload progress at all, so a large file just said
"uploading…". Switched to XHR (upload.onprogress) → real bar + %, and cancel aborts in flight.
#1 Clicking a sender in a group opens a mini profile card (photo, presence, last seen) with a
Message button that opens the 1:1 (and a view-photo button).
#2 Last seen: new users.last_seen column, stamped on connect and when the last socket drops;
carried on the presence broadcast, so an offline contact reads "Last seen 10 minutes ago"
instead of a bare "Offline".
