/* MudAppBar is always `position: fixed`, so page content sits underneath it in normal document
   flow unless something reserves the same space — MudBlazor doesn't do this automatically.
   64px covers the AppBar's tallest (desktop) height; the dense mobile bar (56px) just gets a
   little extra breathing room. `!important` needed for the same inline-style-wins-over-class
   reason as the nav rules above (MudMainContent's own Class="pa-6" resolves to a class, but
   Mud sets its own base padding via a stylesheet rule at a specificity this needs to beat). */

/* DESIGN-SYSTEM.md Accessibility floor: 44x44px minimum interactive target, "including inline
   table-row actions" — measured live (see .memory/logs) that MudBlazor's own control chrome falls
   short of this at every size actually used in this app: Size.Small row-action buttons render
   ~64x31, MudCheckBox's thumb ~37x37, even a default (Medium) button is ~64x37; only default
   MudIconButton (48x48) already clears it. Expand the actual hit area invisibly via ::after rather
   than growing the controls themselves — visually enlarging every row action would blow past the
   40px table-row-height budget DESIGN-SYSTEM.md deliberately set for roster scannability at max
   Program scale (50 students / 100 staff). ".mud-button-root" covers MudButton, MudIconButton, and
   MudCheckBox (all share that base class); MudChip's own delete/OnClose icon (14x14) isn't a
   button-root, so it's targeted separately.
   EXCLUDE .mud-switch-base: MudSwitch's thumb container is a .mud-button-root that MudBlazor
   positions `position:absolute` and translateX-es along the track. This rule loads after
   MudBlazor's CSS, so a blanket `position:relative` here overrode that and broke the thumb layout
   (rendered as a distorted, clipped blob) — the switch's own label already gives it a large hit
   target, so it doesn't need the ::after expansion anyway. */
