/* ============================================================
   home-about.css — About Page
   ─────────────────────────────────────────
   PURPOSE : The About route (html-templates/about/tab-about.html):
             hero with the pointer-following eye, three feature
             cards and the follow banner.
   MOTION  : Entrance animations are pure CSS and replay whenever the
             route is shown (the tab is display:none while hidden).
             Scroll reveal is opt-in — js/about/about-init.js adds
             .about--js, so without script everything is simply visible.
