/* The agent's VOICE (Run 350; Run 360 E3: voice first; Run 362 E3b: voice mode is the PAGE itself — no card) — loaded
   only when the site's voice is on. The SITE's accent only (--accent-rgb, W3): never a rainbow.
   · the FRAME: while the agent listens, thinks or speaks, a margin round the viewport (12 px; 8 px on a phone) filled
     with the brand and lit from its inner edge by a soft, layered light that follows the voice (--sa-level, set by
     voice.js). It is OPAQUE and covers only the page's outermost pixels, so no text is ever read through it (the E3
     glow lay see-through OVER the page and was capped by every line under it). It never takes a click.
   · the CAPTIONS: words straight on the page's foot — a full-width SCRIM rising from the bottom of the window (the
     site's surface, blurred, solid where the words are and fading to nothing above them), never a box, a border or a
     shadow (design critic, Run 362 round 1: a rounded shadowed caption box read as the Sesame card Joel ruled out).
     Large (30 px; 22 px on a phone), at most two lines at a time; the state and the question on ONE small line above.
   · the CONTROL BAR, on the same scrim: "Type", the orb (tap = stop / talk again), "Conversation". Nothing else.
   · the panel: only the typed agent and the transcript ("Conversation").
   · the SOURCE outline: the section the answer came from, for the length of the answer. */
