   office2.css — Office workspace styling
   Powers the Overview, the docs / sheets / slides landings, and the editor
   chrome. It owns NO palette of its own: every colour, surface, shadow,
   radius and accent inherits the app design system (app.css tokens —
   --bg, --text, --primary, --surface, --blend, --shadow, --line, --ui-*),
   so the route looks native to the app and follows the active light/dark
   theme exactly like every other route. The only fixed colours left are the
   three brand hues (Docs/Sheets/Slides) and the deliberate slide themes.
