+ *   vč. svátků  = odpracováno + přesčas
+ *   so/ne       = čisté hodiny směn začínajících v So/Ne (celá směna)
+ *   noc         = průnik s 22:00–06:00 minus pauzy v pásmu, ke dni začátku
+ *
+ * Expected 5/2026 (holidays 1.5. + 8.5.): fond 152 · odpracováno 144 ·
+ * svátek 8 · dovolená 24 · přesčas 17,25 (=17,3 na desetiny) · vč. 161,25
+ * (=161,3) · So/Ne 57,25 · noc 36,75 (payslip said 31 — accountant's own
+ * error, she missed the 31.5.→1.6. overnight shift; 36,75 is CORRECT).
