* * When combined with {ERC7739}, resolution ordering of {isValidSignature} may have an impact ({ERC7739} does not
* call super). Manual resolution might be necessary.
* * Static calls (using callType `0xfe`) are currently NOT supported.
* * Installing a fallback handler for a selector that collides with a function defined on the account (or any
* derived contract) will result in the handler being unreachable, since Solidity dispatches to concrete functions
* before `fallback()`. This includes unrelated function signatures whose 4-byte selector happens to collide.
* The {isModuleInstalled} function only reflects configuration state and does not guarantee selector
* reachability.

* WARNING: Removing all validator modules will render the account inoperable, as no user operations can be validated thereafter.
