/* 4ab.in — ONE FEELING (3.1). The home page and every category page wear this one stylesheet:
   /  /chemistry/ /education/ /spiritual/ /life/ /ventures/ /aniket-bhardwaj/ /ecosystem/ /tools/ /ai/ /projects/
   Owner, 30 Sep 2026: "keep all categories same design … sparkling website with meaning structure … full website in one feeling".

   The structure every page follows, top to bottom:
     crumb → hero (where am I, what is here) → cards (what can I open) → categories strip (where else can I go)
   Colour is the only thing that changes between categories: the group class (k1…k8, hues defined in
   hub-shell.css) sets --accent / --accent-ink / --wash and everything below reads those three.
   Motion is decoration only and stops under prefers-reduced-motion. */
