//! Protocol USDC custody (`treasury` PDA).
//!
//! The treasury serves two roles:
//!
//! 1. **USDC custodian** — the treasury ATA holds all deposited USDC. Deposits come in via
//!    `Deposit`; payouts go out via `AdminPayout` (executor-signed).
//!
//! 2. **Price chain** — `last_close_*` carries the Pyth close price from the most recently
//!    settled period. `AdminInstantSettlement` reads it as the open reference and writes the
//!    new close price back, forming a self-perpetuating chain. Zero until `Initialize` seeds it.
