// verifikat, not räkenskapsinformation: the journal_entries immutability
// trigger (migration 20260608120000) allows a notes-only UPDATE on committed
// entries and rejects anything that touches a bookkeeping field, so this
// schema only has to bound the shape. Max length matches the dashboard
// PATCH route (app/api/bookkeeping/journal-entries/[id]/notes/route.ts).
