/* ============================================================
   Dev Switch site theme

   Type is the app's own face, Poppins, so a page opened from the
   app looks native. Colour comes from the app too: --primary is the Material
   primary in app/src/main/java/.../config/theme/AppColors.kt
   (light 1E7D55 on white, dark 95D3BA on 003829). Type, radii
   and layout follow the KodeElite brand (kodeelite-site repo,
   BRAND.md), so the site still reads as part of kodeelite.com.

   --primary is the fill for buttons, toggles and icons and always
   pairs with --on-primary text. --accent is the same hue used as
   ink for links, eyebrows and tags.

   Light is the default. Dark follows the system preference, or an
   explicit data-theme on <html>, which the app sets through ?theme=
   so the page matches the theme the user chose in Settings.
   Components use these tokens only; no colour literals below.
