/* ── Nav drawer overrides ───────────────────────────────────────────────
   The drawer is a fixed column: header, nav region, pinned footer. It must
   NEVER scroll sideways, and on a 1080p screen the whole admin menu — Setup
   group expanded — has to fit without scrolling at all.

   The menu used to do both. `.mud-nav-link` is `width:100%`, so the old
   `margin: 2px 12px` pushed every link 24px past the drawer's right edge (36px
   for Setup's children, which added another `margin-left:24px` on top of
   MudBlazor's own padding-based indent). That put a horizontal scrollbar on the
   nav region — and because `overflow-y:auto` alone makes the computed
   `overflow-x` `auto` too, there was nothing stopping it. On Windows (classic,
   space-consuming scrollbars, unlike macOS overlay ones) that horizontal bar
   then ate ~15px of height and raised a *vertical* scrollbar on a menu that
   otherwise fitted — the "scrolls up and down for no apparent reason" part.

   So: the horizontal inset lives on the menu container as padding (border-box,
   so `width:100%` links land inside it), sub-items indent with padding only,
   overflow-x is pinned hidden, and the rows are compact enough that the worst
   case — 19 rows, admin with Setup open — fits a Full HD viewport. */
