/* ============================================================
   NetShow footer — mobile collapse (W5-U6, 2026-08-11)
   Scope discipline: every rule is .netshow-footer-scoped; new
   hooks use the .nsf- prefix. Loaded from the footer partial via
   @once, i.e. AFTER footer-v2.css (linked in <head>), so scoped
   higher-specificity rules win the cascade cleanly. The only
   !important flags in this file neutralize pre-existing
   !important declarations in footer-v2.css — never widen them.

   Breakpoints:
     >= 993px  five-column grid (desktop parity with the old inline style)
     577-992px two-column grid (parity with the old !important override)
     <= 768px  accordion collapse + compact chips (script closes columns)
     <= 576px  single-column stack
