/* Blog styles — loaded alongside styles.css, never instead of it. The palette
   variables, .wrap, .section, .btn, .skip-link and the base type all come from
   styles.css; this file only adds what the blog needs.

   Same constraints as the rest of the site: CSP style-src 'self' (no inline
   styles anywhere, which is why the syntax-highlighting classes at the bottom
   exist), no external fonts, dark ops-console aesthetic. */

/* ---------- syntax highlighting ----------
   These classes exist because the CSP is style-src 'self' with no
   'unsafe-inline'. Hugo's default (noClasses = true) emits a style="" attribute
   on every token, which the browser would drop — highlighted code would render
   as flat text. hugo.toml sets noClasses = false so Chroma emits these class
   names instead, and the colours live here where the CSP can see them.
   Deliberately a small subset: the palette has five accent colours, and a
   40-token theme would just be five colours repeated. */
