/*
 * ============================================================================
 * TOKENS
 * ============================================================================
 * The site lives in the app's world, so these are the app's tokens
 * (src/renderer/styles.css in the Edith repo), with a type scale sized for a
 * page you read instead of a dense desktop panel.
 *
 * Rules this file keeps, same as the app:
 *   - radius is always --r (4px); the only exception is a dot (50%)
 *   - surfaces and lines come from the alpha ladder, never a new hex
 *   - colour only ever means state (--live), never decoration
 *   - no box-shadows anywhere
 *   - one easing curve, --ease, for everything that moves
