   1 · status line → headings and display text: Inter Medium, tight.   2 · wordmark → the logotype: Inter ExtraBold, caps, +0.32em.
   3 · URL → labels, kickers, code: JetBrains Mono Regular.             Body and UI: Inter Regular.
   Inter is wider than the condensed serif these sizes were set for; matching x-heights (font-size-adjust) keeps every
   heading's proportions and line breaks. Only type changes here — colours, layout and behaviour are untouched. */
