/* =====================================================================
   Symphonate self-playing product demo — shared styling (v2)
   Mirrors the app's Direction B "Stream" palette (client/src/index.css in
   tdu1/collaborai): deep teal on warm paper, terracotta for the AI.

   v2 adds a desktop three-pane frame (threads rail · thread · Work rail),
   an animated desktop ⇄ phone device transition, and a decision-provenance
   sweep (numbered source-message highlights). Devices are designed at
   fixed pixel sizes (desktop 880×550, phone 356×720) and fitted to the
   embedding iframe with transform: scale() computed in demo.js — so the
   demo renders identically at any embed size.

   Loaded by demos/*.html; the timeline data + engine live in demo.js.
