   Scope: security-surveillance.html only. Loaded alongside the shared
   css/solutions-template.css (hero shell, breadcrumb, chips, overview grid,
   diagram-frame, deployment rail, stat band, FAQ accordion, CTA — all reused
   verbatim from there). Everything in *this* file is specific to this page:
   the radar sweep, the AI detection showcase, the capability explorer and
   the incident-response console. Fully additive — no existing selector is
