/*
 * Echo Dashboard — Design Tokens
 * Single source of truth for all CSS variables, fonts, and shared
 * mobile-modal behavior. Loaded via /echo/static/tokens.css on every
 * dashboard page (in addition to common.css for now).
 *
 * Token coverage:
 *   - Colors (dark default + light theme override)
 *   - Status palette (running, blocked, failed, complete, idle,
 *     planning, pending, approved)
 *   - Typography (Inter sans + JetBrains Mono mono, size scale)
 *   - Spacing (8px grid)
 *   - Radius scale
 *   - Shadows / transitions
