/* CryptoBlog public site: Sahifa-style news magazine theme (SPEC 11), our own code.
   Boxed page on a subtly patterned background, dark menu bar and footer, condensed Oswald labels and
   section titles with a hatched rule, white boxes with a 1px border and a soft shadow, amber where Sahifa
   uses orange. Public Sans for UI, headlines and body text; Newsreader for the post subtitle and quotes.
   Rules: colours only from tokens.css (the theme variables below map to tokens). --accent is a fill behind
   --on-accent text; text links use --link. Hover feedback animates opacity or transform only.
   Mobile first. Breakpoints: 640, 768 (tablet), 1024 (desktop, sidebar beside the content), 1200. */
