/*
 * Bruno Dinamarco Portfolio — design tokens
 *
 * Layers:
 * 1. Primitives describe the visual palette and scale.
 * 2. Semantic tokens describe intent and are the preferred application API.
 * 3. Component/layout tokens capture stable, repeated product decisions.
 *
 * Animation shorthands intentionally keep literal timings in component CSS.
