/* BUKA — design handoff "BUKA visual restyle" (7 Oct 2026).
   Warm paper, charcoal ink, one orange-red accent, one grotesk. Square corners, 1–2 px rules instead of cards
   and shadows. Layout: a 280 px sidebar beside the page; sections are a 240 px head column beside the content.
   Status is never colour only: text, plus a square marker for failures and the verdict. */
