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

     * since the selector defaults to `0x00000000` in the `receive()` function and similarly in the `fallback()` function
     * if no calldata is provided. (See {_checkCanCall}).
     *
     * The `receive()` function will always panic whereas the `fallback()` may panic depending on the calldata length.
