   EdgeBefore, theme X: dark cinematic look
   A layer on top of style.css. Delete the <link> to css/theme-x.css (and js/hero3d.js) in src/layout.html to go back
   to the earlier light look. Inspired by the structure of modern AI-education sites: near-black canvas, slim left icon
   rail, a full-bleed 3D hero, poster banners, white form cards that pop against black. No third-party assets.
