/*
 * all-categories-v2.css — Modern redesign of /all-categories/.
 * Companion JS: all-categories-v2.js
 *
 * Design notes:
 *   - Reuses canonical Guyscat theme tokens (--gc-accent teal, --gc-bg navy).
 *   - Rank-based chip saturation — popular tags pop, sparse tags fade.
 *   - Sticky search bar across the whole page.
 *   - Hero halo: subtle radial gradient behind the title.
 *   - Mobile: jumplinks become sticky pill ribbon, sections stack.
