/* ═══════════════════════════════════════════════════════════════════════
   Module Tool Surface (Track R / R2)

   Shared Relay workspace launcher dock. Any activated module registers its
   tool set via core/ui/module-tool-surface.js; this stylesheet renders the
   floating glass bar and button chrome.

   App-agnostic rule: zero ITGC / Bank / Tax / Pets words, colors, or
   selectors. This file must serve every future module unchanged. Theming
   uses var(--accent) with a safe fallback.
