   AGEWELL ALLIANCE — TOKENS, RESET, BASE TYPE & ANIMATIONS
   Single responsibility: design tokens (CSS variables), CSS reset,
   base typography, all keyframes, and the reveal/animation utility
   classes used by js/main.js IntersectionObservers.

   Load order: this file FIRST. Every later module relies on its
   :root variables and the global box-sizing reset.
