   AutoCops Netgraph — site layout & components
   This file is hand-authored and consumes the variables in theme.css.
   theme.css is generated; site.css is not. Keep all color literals OUT of here
   (use --ng-* tokens) so the brand stays driven by tokens.json.

   Color discipline:
     - Body text reads from --ng-ink / --ng-slate / --ng-muted (auto-flip).
     - Links / eyebrows / success ticks use the *role* tokens
       (--ng-link, --ng-accent, --ng-success) which also auto-flip per theme.
     - Anything sitting on the brand gradient uses --ng-ink (dark) as body text
       so contrast stays >= WCAG AA on every gradient stop (audit in build.sh).
