/**
|
|
* DomainException (Base)
|
|
*
|
|
* Base class for all translatable domain exceptions.
|
|
* Exceptions carry an i18n key + optional args so the application-layer
|
|
* exception filter can translate them into the caller's locale at the HTTP
|
|
* response boundary.
|
|
*
|
|
* Subclasses should:
|
|
* - Pass an i18nKey (e.g. 'error.PORT_NOT_FOUND')
|
|
* - Pass i18nArgs for interpolation (e.g. { portCode })
|
|
* - Optionally override `status` (HTTP status, default 400)
