/* ================================================================
   agent-canvas.css — compact agent editor (maintainer 2026-07-23)
   Built on the app design tokens (css/reset.css) and the modal type
   scale (--arch-fs-* on .arch-view). Each agent is a compact row that
   is COLLAPSED by default (one-line summary) and expands on click to
   reveal the editor. Replaces the old always-expanded "operator" cards.
