/*
 * The Features page -- the plan docs/_plan-fable-features-page-2026-11-04.md, drawn on the approved canvas
 * `design/features/` (owner, 2026-11-04).
 *
 * A STATIC SHEET, like the press page's, so the page looks right without waiting for a rebuild of the asset bundle.
 * TOKENS ONLY: every colour is a `var(--color-*)` of resources/css/app.css (docs/ui-spec.md section 5c). Phone first;
 * `min-width: 1024px` adds the rail and the two columns. No glow, no 3D, no all-caps but the tiny eyebrows (owner).
 * The reveal runs only when `features-page.js` has set `.fx-js`: with no script every word is simply there.
