 * Thrown when `fill()` / `create()` receives an attribute that the model's

 *
 * Zerotal guards by default: a model that declares neither `fillable` nor
 * `guarded` (and has not opted into `static unguarded = true`) rejects every
 * mass-assigned attribute, so a stray `role`/`is_admin`/`id` in a request body
 * can never reach the database. Declare `fillable` to allow specific columns,
 * or use `forceFill()` / `forceCreate()` for trusted, framework-internal writes.
