   WeAdapt Studios — design floor, revision 4 (2026-09-08)

   Source: `weadapt-website/DESIGN-SYSTEM-V2.md`, the studio-oker derived
   system. Everything in that document is applied: grayscale with no accent
   colour, weights 400 and 500 only, no italics, hairlines instead of shadows,
   unrounded photography, short captions, and its section order.

   One deliberate difference: V2 is light-only, and this site was asked twice
   for the inverted version. So the dark ground is the default and the literal
   V2 palette ships as `html[data-theme="light"]`, which is a one-attribute
   switch and nothing else.
