Detailed Description

Exception type for user-facing input validation errors.

Use user_error() when the error is caused by invalid user input (bad CSV data, wrong parameters, missing files). These produce actionable error messages rather than assertion-style crashes.

Use invariant() for programmer bugs (conditions that should never happen if the code is correct).
