+============================
+"Legacy Attendance" — same look/feel as Time Attendance (dashboard,
+records list, Excel export) but sourced LIVE from the old remote MySQL
+server (contract / employee / locations / records tables) instead of
+Excel imports. Read-only: nothing is written to the remote server, and
+nothing is copied into the local database.

+Routes: /legacy-attendance, /legacy-attendance/records,
