/*
 * Features page ("/features/"). Ported from features.astro plus the
 * Tailwind utility classes and scoped <style> blocks of FeatureGrid.astro,
 * FeatureCard.astro, ComparisonTable.astro, and FAQ.astro.
 *
 * Convention: every component has a `data-component` root (matching
 * shared.css); page-only rules are rooted under `[data-page="features"]`.
 *
 * `.fade-in-on-scroll`/`@keyframes fade-in-up` moved to shared.css (Phase 3):
 * this page used to carry its own byte-for-byte copy of that rule, now
 * centralized since features/install/demo/skill/how-it-works all used it
 * identically. `fade-in-observer.ts` (plain JS) adds the `.is-visible`
 * class the shared rule now gates the animation behind.
