   thomas-knorr.io — site styles
   v0.2 · Design-system-aligned (knorr. v0.1, April 2026)
   Imports `colors_and_type.css` from the DS as the single source
   of typographic + color tokens. Adds only app-specific layout.
   Invariants enforced:
     • paper #F5F2EC is NOT white
     • ink   #141414 is NOT black
     • accent #C4552D is SINGULAR per surface
     • no shadows, no blur, no gradients, no pills
     • hover: color shift only (no scale, no glow, no bg-tint)
