/* WOLF AI — the Workspace layout. Loaded after style.css; every rule that reaches into the
   classic screens is gated on :root[data-ui="chat"], so the classic layout is untouched.

   How it works: the classic screens are built from design tokens (--ink, --paper, --line…), so
   this file re-points those tokens at a zinc palette with one emerald accent and the evidence,
   review, search and activity screens re-skin themselves inside the new shell. Only the sidebar,
   the project page, the thread and Settings are new markup (.cw-*, built in chatui.js).

   Semantic colours are kept: --held (amber) still means "held", --danger still means an error. */
