/* Vizion Render Upgrade — hoja UNICA del widget.
 *
 * POR QUE EXISTE: hasta el 2026-09-07 este CSS estaba escrito DOS veces, una en
 * index.html y otra en render-upgrade.html. Un arreglo hecho en una no llegaba a
 * la otra; ya habia pasado con el comparador del upscaler, que se quedo sin la
 * manija para arrastrar porque le faltaban reglas.
 *
 * POR QUE EL MISMO CSS ESTA DOS VECES ACA ADENTRO:
 * el home envuelve todo en #vizion-app y tiene reglas globales que le ganan a un
 * selector de una sola clase; la landing y el canvas NO tienen ese contenedor.
 * Se emite el bloque tal cual (gana en el home por especificidad) y de nuevo sin
 * el prefijo (unica forma que aplica fuera del home).
 *
 * ⚠️ NO transformar selectores con una expresion regular. Se intento y se
 * perdieron 14 reglas: las que estaban dentro de @media y la primera de cada
 * bloque no matcheaban, y el resultado quedaba mal formado. Duplicar el texto
 * entero es feo y es correcto.
