   Thirty3D Cotizador 3D — estilos del cotizador (rol ux-ui)
   - Todo con prefijo .t3d- y colgado de .t3d-app para aislarlo del tema.
   - Móvil primero: una columna; dos columnas (visor | opciones) desde 900 px.
   - El acento lo aplica el JS desde T3D_CONFIG.viewer.accent:
     --t3d-accent, --t3d-accent-ink (texto sobre acento), --t3d-accent-strong
     (acento oscurecido con contraste AA sobre blanco) y --t3d-accent-soft (fondo suave).
