/*
 * CSS-ONLY-CONSUMES / JS-ONLY-WRITES CONVENTION
 * ─────────────────────────────────────────────
 * CSS rules in this file CONSUME custom properties (var(--name)) but never WRITE them.
 * JS in script-v2.js WRITES custom properties but never reads computed CSS values.
 *
 * Examples:
 *  - --scroll-progress: written by scroll listener, consumed by .scroll-progress::after + .pinned-scrub-track
 *  - .revealed class:   added by IntersectionObserver, consumed by [data-reveal].revealed
 *  - .active class:     added by nav-spy IO, consumed by .nav-links a.active
 *
 * Keep the contract clean: any new scroll-driven effect should follow the same pattern.
 * If you find yourself reading computed styles in JS, stop — set a custom property instead.
