/* ===========================================================================
   Yappit — one stylesheet for the whole site.
   ---------------------------------------------------------------------------
   Every value here is the app's own. The colours come from lib/theme/brand.dart
   and the launch gradient in yappit_login_v2_view.dart; the typefaces are the
   two the app actually ships (Sora for headings, Nunito Sans for body, see
   lib/theme/app_theme.dart). Nothing was invented to look "web".

   The site is dark on purpose, not for fashion: Yappit is a black OLED app and
   a visitor should recognise the product before they read a word. So there is
   no light theme to switch to - every colour is painted explicitly and the
   page holds on any host background.

/* ===== Motion ============================================================
   Two tiers, and the page is complete without either.

   TIER 1, everywhere: a one-shot fade when an element first enters, driven by
   an IntersectionObserver. This is the floor.

   TIER 2, where the browser has scroll-driven animations: the same reveals
   plus the action cards and the hero parallax become SCROLL-LINKED. The
   difference is not decorative. A time-based animation fires near the right
   moment and then plays on its own schedule, so scrolling back up shows
   nothing and a fast flick shows it half-done. A scroll-linked one is a pure
   function of scroll position - it tracks the scrollbar exactly, reverses
   when you scroll back, and runs on the compositor, off the main thread.
   Chrome/Edge 115+, Firefox 132+, Safari 18+.

   Tier 2 is behind @supports, so a browser without it keeps tier 1 and
   nothing is ever left parked invisible. ================================= */
