   PSD International — site stylesheet (2026-07-14 redesign)
   Identity: engineered, premium defense-industrial. Ink base + warm brass
   accent + bone/paper section band. Color-blocked ink -> paper -> ink.
   Type: Archivo (industrial grotesque display) + Public Sans (USWDS workhorse).
   Strict CSP compatible: no inline styles, all rules live here.
