/* =================================================================
   Network & CCTV page.
   Built ON TOP of the shared kinetic system (webdesign.css / body.wd-dark):
   inherits the dark tokens, header/footer theming, wd-* sections and reveals.
   Page-specific parts use nc-* (content) and ncx-* (the interactive NOC
   dashboard in the hero). Cards use var(--card/--fg/--line/--muted) so they
   adapt automatically between dark and .wd-light sections.
