   UNIQorn — article.css
   The editorial surface: a single post, its archive list, and the
   related/navigation chrome around the body.

   Base is exactly var(--white) (checklist A2). Separation is always a 1px
   hairline, never a colour block. Typography sits on the same foundation
   the rest of the site uses; entry-content's rules live in foundation.css
   so a single source of truth governs prose wherever it appears.
