/* =========================================================
   COSMIC AGENTS — Workspace (/studio)
   Extends landing.css (tokens, nav, buttons) and demo.css
   (Markdown, message anatomy, chips, model picker, tabs).

   Layout: three columns filling the viewport, each scrolling
   on its own - saved conversations | the thread + composer |
   the crew's work. Below 1180px the crew panel becomes a
   drawer; below 820px the conversations do too.
   Colour roles as on /demo: gold = the answer, violet = the
   crew's own record, cyan = sources and deep research.
