/* ---------- MARCADOR TEMPORAL DE REVISIÓN (qa-nuevo) ----------
   Envuelve exclusivamente las piezas nuevas/modificadas de la ronda de
   mejoras en curso, para que el usuario las identifique visualmente
   mientras confirma que funcionan. NO es diseño final:
   - Si se aprueba una pieza: quitar la clase "qa-nuevo" de su marcado.
   - Si se rechaza: retirar la función completa (no solo el estilo).
   No altera lógica ni datos, solo apariencia. */
