/* ═══════════════════════════════════════════════════════════════════════════
   ลงเวลาปฏิบัติงานด้วยตำแหน่ง — qr_checkin_v2.php
   2026-09-25 first version · 2026-10-02 site language (blue header, Sarabun + display font)
   2026-10-07 commercial-grade time clock:
     a round time-clock button whose ring shows the location state (body[data-loc]),
     a small radar of the school's radius, today's work line with hours worked so far,
     this week Mon–Fri and this month's totals, and a two-pane layout on wide screens.
   Every selector is prefixed ci- so this sheet cannot collide with the rest of the module.
   Mobile first. Text colours meet 4.5:1 (large text 3:1) in light and dark.
   tb1-app.css swaps --ci-sans/--ci-serif to Sukhumvit Set inside the TB1 app and gives
   .ci-clock, .ci-sched b and .ci-t dd a system font with even digits: keep those class names.
