/* ── Compact icon-only tabs on phones (Back Office / Analytics) ───────
   MudTabs renders every tab header in one row and horizontally scrolls
   it (via a JS-calculated transform, not native overflow) once it's wider
   than the viewport — which is every time on a phone, since 6 tabs at
   ~110-160px each add up to 700-960px. MudBlazor's own scroll-into-view
   math can overshoot when a tapped tab is more than one position away,
   leaving the visually-highlighted header out of sync with the (still
   correctly rendered) active panel below it. Rather than patch that
   compiled 3rd-party scroll logic, we remove the need to scroll at all
   below 600px: icon-only tabs are narrow enough that all 6 fit in one
   screen width, so the buggy scroll path never triggers. Each tab's
   full label survives as its native title/tooltip (see ToolTip on each
   MudTabPanel) and stays visible from 600px up (tablet/desktop).
   Requires each MudTabPanel to use a <TabContent> with a "rw-tab-label"
   span instead of the plain Text parameter — MudBlazor renders Text as a
   raw sibling text node with no wrapper element we could otherwise target. */
