   The palette mirrors the Flutter app's semantic theme tokens
   (../frontend/lib/core/theme/app_theme_colors.dart): :root holds the
   light-mode values — the default — and the .dark class on <html> swaps in
   the dark-mode values, so the page re-skins itself exactly like the app.
   The switch in the nav toggles the class and persists the choice in
   localStorage (see index.html). Components only reference the tokens
   below — never raw colors. */
