manko = max(0, fond − (worked_total + dovolená + nemoc + neplacené volno))
using REAL clock time, not the paušál. Supplement next to Přesčas — the
verified binding formulas are untouched.
Why: the paušál Odpracováno can nominally cover the fond while dozens of
real hours are missing (Dominik 6/2026: 21 days × 8 + 8h dovolená = 176 =
fond exactly, thanks to weekend shifts compensating 3 recordless weekdays —
yet real worked time was 136,5h). Přesčas = 0 correctly, and the 31,5h gap
vanished from every total. Now it's a permanent summary line, red+bold when
positive, plus a 'Chybí: Xh' chip on the admin screen cards.
+4 tests incl. the real June dataset as a pinned acceptance case (also
pins noc 6,75 — early shifts starting 05:30/05:45 legitimately count
night minutes before 06:00).
