/* Docs panel (Q, task queue #28). Same tokens and primitives as style.css:
   the projects down the left (a chip row when narrower), the documents in one
   card per project on the right. The one new colour rule: each format keeps
   the hue people already know it by (Sheets green, Docs blue, PDF red...),
   muted to sit on the dark canvas, and only on the format's own icon. */
