/* ── El atributo `hidden` gana a las utilidades de display ─────── */
/*
 * Bootstrap declara `[hidden]{display:none!important}` cerca del principio de su hoja y las
 * utilidades `.d-flex` / `.d-inline` / `.d-block` cerca del final, todas con `!important` y la misma
 * especificidad (0,1,0): gana la última, así que un elemento con `class="d-flex" hidden` se veía
 * igual. El proyecto usa el patrón «pintar siempre y alternar con `hidden`» en varias pantallas
 * (el aviso de retiro de D-22 en la ficha de la CxC, el formulario de reiniciar nota, los avisos de
 * la card de cuenta), y ahí el atributo era inerte.
 *
 * Esta hoja se carga DESPUÉS de Bootstrap, así que esta regla lo resuelve en un solo lugar en vez
 * de cambiar cada marcado. Detectado en la ronda 2 de la revisión de cierre de la Fase 4.
