 *
 * - `valueTokens`: tokens whose balances count toward total redemption reserves.
 * - `activePayoutToken`: token actually paid out by redemption modules.
 * - `scheduledPayoutToken`: pending token to become active at next UTC midnight (`switchTime`).

 * **Security considerations**
 * - Only authorized operators (via {AccessManaged}) may configure or switch tokens.
 * - `emergencySwitch` bypasses the schedule and should be protected by a guardian role.

     * ====
     *
     * [WARNING]
     * ====
     * Avoid adding this modifier to the https://docs.soliditylang.org/en/v0.8.20/contracts.html#receive-ether-function[`receive()`]

     * since the selector defaults to `0x00000000` in the `receive()` function and similarly in the `fallback()` function
     * if no calldata is provided. (See {_checkCanCall}).
