/* RememRx marketing site, design tokens mirror lib/core/theme/app_theme.dart
   exactly (AppColors / AppSemanticColors, dark variants), and the type
   pairing (Figtree for headings/labels, Noto Sans for body) matches
   AppTheme._buildTextTheme, so the site reads as the same product as the
   app, not a reskin.

   Dark only, deliberately. This used to ship light tokens here with a
   `@media (prefers-color-scheme: dark)` override, which meant the page
   followed the visitor's OS setting. The app itself now defaults to dark
   (theme_mode_provider.dart), and every marketing screenshot is a dark
   capture, so on a light-mode machine the old setup put dark phone
   screenshots on a light page and showed something other than what a new
   user actually gets on first launch. Locking the palette keeps the site,
   the screenshots, and the product's own default in agreement.

   Do NOT reintroduce a prefers-color-scheme block: it would reopen exactly
   that mismatch. */
