/* ============================================================
 * guia-components.css — ANDAMIAJE COMPARTIDO de las guías públicas
 * (scroll abierto, ADR 0020). FUENTE DE VERDAD ÚNICA.
 *
 * Capa local sobre el design-system vendoreado (tokens). Clases
 * neutras `guia-*`: el LOOK & FEEL del andamiaje (hero, escalón,
 * mini-check, práctica, faq, footer…) vive aquí, idéntico para
 * todas las guías. Lo específico de cada tema (visual del concepto,
 * widget interactivo, leyenda de color) va en el `theme.css` de la
 * guía, NUNCA aquí.
 *
 * REGLA DE GOBERNANZA: este archivo es "cambio de sistema". Editarlo
 * propaga a TODAS las guías y debe hacerse una sola vez, aquí. Una
 * guía nunca redefine `guia-*` en su theme.css.
 *
 * Regla CSS+KaTeX: fondos de píldora/badge SOLO en `> span`
 * (hijo directo), nunca descendiente.
