 * Covers the 9 design screens:
 *   1. Lobby (hero, continue cards, stats, modes-grid, friends, history)
 *   2. Matchmaking (radar, params)
 *   3. Game (eval-bar, right rail, moves, opening, chat)
 *   4. Result (verb, delta, ribbons)
 *   5. Tournaments (featured, list)
 *   6. Puzzles (board+side, streak, categories)
 *   7. Watch (featured, grid, mini-boards)
 *   8. Leaderboard (podium, table)
 *   9. Profile (hero, openings, achievements)
 *
 * Generic primitives (board, sidebar, topbar, buttons, chips, stat tile,
