/* ============================================================================
   Verse AI composer (js/verse-ai-composer.js, js/verse-ai-capture.js). Reference: docs/VERSE-AI-COMPOSER.md.
   Loaded after chat.html's own rules and built on the page's theme variables (--bg-*, --text-*, --border-*,
   --primary-color), so every theme of the page themes the composer too.

   What colour means here:
     orange (--vac-studio, Verse Studio's own accent)  the prompt goes to Verse Studio and costs VXT
     the page's primary colour                         it goes to the AI with research
     violet (--vac-build)                              Build mode
     red (--vac-rec)                                   the microphone or camera is recording
   Shapes: a circle acts (+, dictate, send), a rounded chip is a setting, the tag at the start of the prompt is the tool.
   The capture surface is the one place that leaves the theme: it is always dark, like a viewfinder.
   Bump ?v= in chat.html on every edit.
