   AYChat — homepage only. Loaded after site.css, which owns the palette,
   topbar, cards, buttons and footer.

   Everything here is hand-built CSS: the phone in the hero is markup, not a
   screenshot, so it stays sharp on every display, weighs nothing, and never
   goes stale when the app's UI changes.
