/* ============================================================
   Simón — tablero y portada (templates/play_simon.html, simon_hub.html).

   El tablero es un disco oscuro con cuatro cuadrantes (rojo, azul, verde,
   amarillo, como en el banner) y un centro con el nivel. Cada color tiene
   su tono en reposo y encendido; el encendido se funde en ~110 ms y se
   apaga más lento (no destella). Todo lo demás usa los tokens de app.css.
