/* ============================================================
   protect.css — copy + screenshot deterrents (client-side only).

   HONEST LIMITS (read before relying on this):
   • Copy protection here is STRONG against ordinary visitors, but a
     developer with DevTools / "View source" / curl can still read the
     delivered HTML. Nothing served to a browser can be made unreadable.
   • Screenshots CANNOT be blocked by any website on Windows, macOS,
     Linux, Android or iOS — the capture is handled by the operating
     system and the page never receives the event. All we do here is
     DETER: blur the page when the window loses focus. Determined
     capture always succeeds.

   Form fields, the footer contact block, and anything marked .selectable
   stay fully usable.
