--- Attendance state expansion — spec section 16.
---
--- The visual state system needs vacation as a first-class state alongside
--- present / absent / late / excused. "Not yet marked" is the absence of a row,
--- so it needs no enum member.
---
--- Enum values cannot be used in the transaction that adds them, and the
--- Supabase CLI wraps each file in one transaction, so this file adds values and
--- nothing else. 20260807001300 is where they are used.
