/* ICAO Level landing: the blog (/blog/ and its articles). The article area is a one-to-one port of the atpl.com.tr blog
 * template ("Editorial Cockpit": a dark hero with breadcrumb, eyebrow, big title and meta row; a sticky table of contents
 * beside the prose; lead, takeaways, callouts, numbered H2s, .wtable tables, FAQ accordion, dark CTA cards, the demo quiz;
 * the hub's card grid) with the same fonts (Geist, IBM Plex Mono, Newsreader), type scale and spacing.
 * Loaded after site.css, only on blog pages. Everything is scoped under main.blog (and body.blog-sayfa for the page
 * ground), so the ICAO Level header, footer and cookie banner keep site.css's look. Accent: on light surfaces the ICAO
 * blue sits where atpl uses its navy; on the dark hero and CTA cards amber sits where atpl uses its light blue.
 * Two themes like site.css: the light one below, the night one when the system is dark (unless the visitor chose
 * light) or the visitor chose dark. */
