/* GodEngine Decision API (godengine.io)
   Concept: "the record". The site reads like an engineering ledger: numbered
   sections, a mono-led type scale, drafting-paper grid in light mode and a
   night-ledger in dark mode, GodEngine gold (hue 82) as the only brand accent.
   No external fonts, no inline styles. Works under default-src 'self'. */
