/* ─────────────────────────────────────────────────────────────────────────
 * design-systems/replicate/tokens.css
 *
 * Structured token bindings for "Design System Inspired by Replicate".
 * Developer playground: explosive gradient energy, pill-shaped geometry,
 * massive display typography, high-contrast black/white + red brand.
 *
 * Key brand decisions encoded here:
 *   - Pure white body canvas with Replicate Dark (#202020) for text/borders
 *   - Replicate Red (#ea2804) — brand accent for gradients and accent borders
 *   - EVERYTHING is pill-shaped (9999px) — the absolute design commitment
 *   - rb-freigeist-neue at weight 700 for display — thundering headlines
 *   - basier-square at weight 400 for body — quiet counterpart to heavy display
 *   - Links use dotted underline (#bbbbbb) — developer notebook aesthetic
 *   - Depth via borders and background color, not shadows
 * ─────────────────────────────────────────────────────────────────── */
