The page+component MUI migration has dropped all usages of these
stylesheets' classes. Verified by grep over src/**/*.{ts,tsx}: none of
their selectors are referenced as a className token anywhere.
Removed files + their imports from AdminApp.tsx:
forms.css, buttons.css, components.css, tables.css, datepicker.css,
filemanager.css, pagination.css, responsive.css, dashboard.css,
settings.css, invoices.css, warehouse.css
Kept: variables.css, base.css, plan.css (foundation), attendance.css
(live .attendance-location-map Leaflet container) and offers.css (live
.admin-rich-editor / .admin-rich-text-view + .ql-* Quill snow overrides).
The standalone <div className="admin-spinner"> in App.tsx remains styled
by base.css (buttons.css only held .admin-btn-scoped spinner modifiers).
Gates: tsc -b --noEmit (0), npm run build (ok), vitest (150 passed).
