/*
 * Design system — Archivo La Semanal (site only)
 * Official brand palette from "LA SEMANAL con la Prensa" artwork.
 * Active Admin styles live in active_admin.scss and must never be required here.
 *
 * Core brand:
 *   Navy   #00296B  — primary surfaces (nav, footer, headings)
 *   Red    #E33045  — CTA / emphasis
 *   White  #FFFFFF  — surfaces & text on navy/red
 *   Sky    #4A90E2  — secondary accent (stripe / focus)
 *
 * Visual direction: digital news archive — dense desktop grid, serif headlines,
 * content-first columns. Colors stay on-brand.
