   Brand: Born R2 Look-and-Feel (May 2026).
   Palette: Clarity / Nuance / Volume — strict.
   Typography: STK Bureau Sans / STK Bureau Serif / STK Miso Black.
   Aesthetic: editorial minimalism, magazine grids, annotation callouts.
   Hierarchy is built from size, weight and negative space — never colour.

   fills the hero exactly via `width:100%; height:auto`. No cropping,
   no empty space. The square sits naturally at 79.54% of the viewport.

   Below 960px: hero height fixed at 320px; the image renders at its
   natural aspect (width 960px). It is positioned so the right edge
   stays at the viewport right edge (cuts in from the left) until the
   viewport narrows enough that the square would land left of centre,
   at which point centre-anchoring takes over and crops both sides
   equally. The max() of the two anchor formulas selects whichever
