/* =========================================================================
   AURORA — shared component layer for inner pages
   Loads on any page tagged `.ap-aurora-page` (currently: About). Carries the
   reusable primitives that the bespoke homepage keeps inline in home.css:
   aurora field, glass, buttons, reveal motion, newsletter, portrait, etc.
   Pairs with assets/js/reveal.js.

   NOTE: home.css still ships its own copy of these primitives so the homepage
   renders byte-identical to before (it does NOT load this file). When you're
   ready, the homepage can switch to aurora.css + a trimmed home.css and the
   duplication goes away. Until then keep shared changes in sync across both.
