Animated bars, inline ProdCom timestamps, fullscreen auto-fit, dual resize corners

Title bars (tiles and the main menubar, which gains the same notch tab)
now collapse and reopen with a height animation instead of popping. The
menubar's hidden state persists per browser. ProdCom timestamps move
inline to the right of the channel name, keeping their text style; the
clock button toggles just their visibility. New fullscreen button (left
of ＋): entering fullscreen auto-hides the menubar and auto-fits the
layout — occupied columns stretch proportionally across the width, tiles
whose bottom edge lands within two rows of the viewport bottom stretch
to end exactly at it, small tiles (h ≤ 2) alone in their columns are
exempt, and scrolling is disabled when nothing extends below the fold
(deeper layouts keep natural rows and scrolling). All fullscreen fitting
is visual-only and reverts on exit; editing affordances are parked while
in it. Corner resize indicators now appear only on tile hover, and a
second resize handle on the bottom-left corner resizes from that edge.
