   width+height and letting noVNC's resize=scale letterbox inside it
   (which wastes space whenever the box's own shape doesn't match
   8:5), size the box itself to that exact ratio via aspect-ratio, and
   let width/height both come from whichever of "100% of the
   available width" or "available height, convertex to width via the
   ratio" is smaller — that's the largest size that fits either

   changes size). .vnc-frame-wrap is the actual content: 100% of
   .vnc-scroll normally, but the mobile zoom buttons grow it past 100%
   via JS (app.js), which makes it overflow .vnc-scroll and become
   natively scrollable/pannable — same mechanism as zooming into any
   oversized image in a scrolling div, nothing exotic. Desktop never

   same as the "computer works great, don't change it" ask.

   The point of this block: the desktop topbar is two full-height rows
   of padding/font-size that cost ~90px. On a landscape phone, total
   viewport height might only be ~360px, so that fixed 90px eats a huge
   share of it and leaves the vnc box starved for height — which is
   exactly why rotating to landscape didn't visibly give a wider game
   view before (the box is aspect-ratio-locked to 8:5, so it's capped by
   whichever of width/height is tightest, and height was the bottleneck).
   Shrinking the topbar here, and shrinking --topbar-budget to match,
   gives that height back to the box. */
