/* Green Claims Audit (UK edition) — forensic-editorial "redline" aesthetic.
   Sibling of the EU site: same type + palette. Scores claims against the CMA
   Green Claims Code + the DMCCA 2024 (in force 6 Apr 2025).
   Type: Fraunces (characterful serif display) + Libre Franklin (grotesque body) + Spline Sans Mono
   Palette: warm bone paper + ink + signal red (flagged claims) + restrained olive.
   Deliberately NOT "eco green" — this is about scrutiny OF green claims. */
