/* ===========================================================================
   AZZA Medical — one stylesheet, generated-adjacent but hand-authored.
   Miami ocean: deep Atlantic navy, Miami aqua, sunset coral, warm sand.

   Two rules that are load-bearing here, both learned the hard way:
   1. Reveal animations FAIL VISIBLE. The hidden state is only ever applied
      under html.reveal-on, which JS sets after it has proven it can also turn
      things back on. No JS, a throttled IntersectionObserver in a hidden tab,
      or a script error all leave the page fully readable.
   2. Nothing here relies on a third-party stylesheet or font host.
