/**
 * Subtle scroll-reveal + hover polish. Replaces the Round 16 shader-gradient
 * background and liquid-glass cards entirely -- both were called out as
 * "ugly" (the dark navy/gold moving background, and the murky glass panel
 * look), so this round is a full swap to a much quieter approach: gentle
 * fade/slide-ins as the page scrolls (AOS) and light, tasteful hover
 * states -- no 3D, no WebGL, no glass.
 *
 * Kept in its own small file, same as before, so it's easy to find/diff/
 * remove independently of resource-hub.css.

/* ---- Hover polish -----------------------------------------------------
   Deliberately hand-written rather than pulling in Hover.css: that
   project's free tier is licensed for personal/open-source use only, not
   commercial use, and it wasn't worth the licensing ambiguity for a dozen
   lines of CSS this site actually needs. These are original, simple
   transform/shadow transitions -- nothing borrowed. */

/* Buttons and CTA links: a gentle lift, matching the resource card's own
   existing hover treatment (see .resource-card:hover in resource-hub.css)
   so the whole site feels like one consistent language rather than two
   different hover styles competing. */
