/* /connect/admin/views/attendance.css — Admin Attendance view v1
 *
 * "Vibrant Community" skin for the admin Attendance view (attendance.js).
 * Scoped under `.atadm-view` (plus the `#atadm-ci-*` overlay, which mounts
 * on <body>) so it never leaks into other admin views.
 * Requires: /shared/tokens.css, /connect/connect-tokens.css,
 *           /connect/admin/admin-shell.css, /connect/admin/admin-views.css
 * Loads AFTER admin-views.css so it refines the legacy `.atadm-*` rules.
 *
 * Only intentional literal hex used: #fff (on-gradient / on-solid ink).
 * ─────────────────────────────────────────────────────────────────── */
