/* ⚠️ SCROLL GUARD — DO NOT add overflow:hidden to html, body, or main containers.
   This has caused 4+ regressions: #1515954, #1524323, #1524842, #1534925.
   If you need overflow:hidden for a specific component, scope it to that component ONLY.
   Only body gets overflow-x:hidden (line ~247). Do NOT set overflow on html —

   FIX: Admin nav bars and tab bars get cut off on narrow screens because
   body has overflow-x:hidden (correct for the page) but nav containers
   had no independent scroll context. This adds horizontal scrolling to
   common nav/tab wrapper classes on mobile so all items are reachable
   by swiping left/right — while the page itself stays locked.

   Does NOT force flex-wrap:nowrap — pages that intentionally wrap their
   nav items (e.g. admin-roles, admin-users) keep wrapping. The overflow-x
   only activates when content actually overflows.
