// Create the `cash_float_entries` PocketBase collection (idempotent).
//
// The cash-float CARD: one opening balance, then every slip subtracts from it. Stored as a
// ledger — the balance is the SUM of entries, never a number that is overwritten — so every
// rand on the card can be traced to a slip.
//
//   kind "opening"  the balance on the card when tracking began (set once)
//   kind "topup"    money loaded onto the card later
//   kind "expense"  a slip: supplier, cost code, comment, amount and the photo of the slip
//
// `amount` is always positive; the kind decides the sign. Not wiped by the seed.
//
// Usage: node scripts/setup-cash-float-collection.mjs
