/* Shared stylesheet for the static, indexable pages (`/`, the tenant site and
   the two legal documents). These pages are plain HTML on purpose — Flutter
   web paints into a <canvas>, so nothing it renders is crawlable. See
   `.ai/SEO.md`.

   Colours mirror `packages/theme/lib/src/color_styling.dart`. They are
   duplicated here rather than generated because these pages ship without the
   Dart toolchain; if a brand colour changes there, change it here too.

   Light only, on purpose. `ThemeController.load()` sets dark from a stored
   preference and nothing else — `isDark = stored == 'dark'` — so it never
   follows the operating system, and a first-time visitor to the Flutter
   pages always saw light. A `prefers-color-scheme` block here would put a
   page in dark that the app itself would have shown light, and would hide
   the logo, whose SVG paints a fixed `#232673`. */
