/* Styles for the article reading page (/articulos/<slug>/).
 *
 * WHY THIS FILE EXISTS, AND WHY IT DUPLICATES VALUES
 * --------------------------------------------------
 * Every other page on this site is built by Next and styled with Tailwind.
 * This one is assembled by netlify/functions/articulo.js at request time, so
 * that an article published in /admin is live immediately rather than waiting
 * for someone to run a deploy. A function cannot use Tailwind classes — they
 * are generated when the site is compiled — so the reading page carries its
 * own stylesheet.
 *
 * The colours below are copied from tailwind.config.ts and app/globals.css.
 * IF YOU CHANGE A BRAND COLOUR THERE, CHANGE IT HERE TOO. There is no build
 * step that will catch the drift for you.
 *
 * Same story for the fonts: app/layout.tsx loads them through next/font/local,
 * which publishes them at hashed paths that change on every build, so this
 * page points at the stable copies in public/fuentes/ instead.
