Phase 2 of the "fully MUI" cleanup — eliminates two more stylesheets.
- base.css -> src/admin/GlobalStyles.tsx: the reset, typography,
scrollbar/::selection, theme cross-fade timing and all utility
classes now live in a single theme-aware MUI <GlobalStyles>, rendered
inside MuiProvider so every rule resolves against theme.vars (verified
reactive in both schemes). base.css deleted.
- attendance.css -> a styled("div") LocationMap in AttendanceLocation;
attendance.css deleted.
- App.tsx bootstrap loader is now fully self-contained (inline spinner
+ keyframes, theme-aware background read from the data-theme attr),
since it renders before MuiProvider/GlobalStyles mount — it no longer
depends on the removed .admin-spinner / var(--bg-primary).
tsc -b --noEmit and npm run build clean; verified in Chrome (light +
dark): body bg, text, fonts, .text-warning/.link-accent all correct.
