/*
 * Charmeleon UI — shared base stylesheet (redesign 2026-08-02).
 *
 * Direccion visual: "instrumento de precision" (la de la landing), no HUD
 * generico. Todos los nombres de clase del port anterior se conservan: los
 * tests y las rutas viejas los referencian; aqui solo cambia como se ven.
 *
 * Reglas que esta hoja aplica (ver tokens.css):
 *  - acento solo en interaccion; los datos van en blanco/mono
 *  - secciones separadas por hairlines, no todo metido en cards
 *  - eyebrows mono uppercase como rotulo de seccion (mismo device que la landing)
 *
 * Depends on: tokens.css (must be loaded first).
