   Tester: "Looks like the UI was built for a mobile phone... It would be

   block ADDS a wide-screen treatment above ~900px, it never overrides
   anything below that breakpoint. Typing is the primary input on a laptop
   (a keyboard is right there), so the compose textarea gets the emphasis:
   a comfortable max content width (not full-bleed - long lines are
   unreadable), a genuinely wide multi-line answer box, and more vertical
   room for the transcript. The push-to-talk button stays available but
   drops to a small, secondary-looking control instead of competing with
   the text box for space - the existing min(40vw, 300px) mobile rule
   already caps it at 300px past a 750px-wide viewport, but 300px is still
   sized to be the dominant control on a phone; a laptop wants it visibly
   secondary, not merely capped.
