/* Familiai — familiai.in
   ---------------------------------------------------------------------------
   Rebuilt to show rather than tell. Each section is one short headline and one
   animation that demonstrates the claim; the prose that used to explain it has
   either moved to /privacy and /support or been cut.

   Every animation is driven by an `.in` class added when the section scrolls
   into view, so nothing moves off-screen and a reduced-motion visitor gets the
   finished state with no motion at all.

   Two accent hues, one per speaker. They are the only colour in the design that
   carries meaning. No webfonts and no third-party requests. */
