/* =========================================================================
   s7s — Secure, so you can stop worrying about it (SECURITY)
   Split out of the old s7. Layout archetype: CENTRED, abstract, NO device frame
   (alternates from the s7b SPLIT local-search visual that follows).
   Signature motion (ONE): a single scrubbed proxy --charge (0 -> 1) on .s7s-stage.
   Everything derives from it:
     - the four protection checks ignite gold ONE AFTER ANOTHER (each box keys off
       --charge against its own --i staged threshold)
     - the shield body brightens and its tick draws LAST
   Transform / opacity / stroke-dashoffset only. Reduced motion + no-JS force
   --charge:1 so the section rests fully charged and readable.
