/* Hub finish, shared by /guides/, /faq/, /glossary/ and /analysis. Five palette families colour the five topics: brand pink, success green,
   warm bronze, error coral and plum. Each topic carries --c (fills and glows) and --ct (text, dark enough to read on light). A drifting
   gradient aura sits behind the hero, stats count up, the path draws itself, and cards light up under the cursor and rise in on scroll.
   Behaviour is public/guides/hub.js; without it everything is simply visible. */
