   (October 2026): a pale-to-deep teal gradient hero, white floating cards,
   pill buttons, a light grey content band and a cream closing band, set in
   Inter with Be Vietnam Pro for headings. The colours are measured from that
   page, with one change: text and buttons use --teal-ink, a deeper shade of
   the same teal, because white on the original #5AA9B5 is too faint to read
   comfortably (2.7:1). The gradients keep the original. */
