// v1.4.16 Wave-C MED — horizontal tab strips overflow viewport on
// mobile when more than ~3 tabs render at typical label widths
// (`/insights`, `/admin`, `/settings/*`). Tab labels are i18n-driven
// so we cannot truncate them deterministically. Instead, the list
// becomes horizontally scrollable on mobile via `overflow-x-auto`
// plus `touch-pan-x` for the iOS PWA, and the wrapping tabs preserve
// `whitespace-nowrap` so labels never word-wrap mid-tab. Desktop
// looks identical because the inline-flex shrink-wraps inside the
// wider container.
//
// v1.4.19 A7 — `overflow-y-hidden` clamps the y-axis. Browsers couple
// the two overflow axes once one is `auto`: setting only
// `overflow-x: auto` silently flips `overflow-y` to `auto` as well.
// Combined with the fixed `h-9` strip and badge children that ride
// ~1 px taller than the strip on some glyph stacks, a tiny painted
// vertical scrollbar appeared on the right edge of short strips
// (e.g. the admin feedback `Open / Acknowledged / Resolved /
// Archived` tabs the maintainer reported in v1.4.19). Locking the y-axis hides
// that bar without affecting horizontal swipe behaviour.
// Padding sits at `p-1` (4 px) so the 3 px focus-visible ring
// (`focus-visible:ring-[3px]`) on triggers stays inside the
// `overflow-y-hidden` clamp without clipping the bottom of the ring.
