// A mailer can provide two Zmpl templates for rendering email content:
// * `src/app/mailers/<mailer-name>/html.zmpl
// * `src/app/mailers/<mailer-name>/text.zmpl
//
// Arguments:
// * allocator: Arena allocator for use during the mail delivery process.
// * mail:      Mail parameters (from, to, subject, etc.). Inspect or override any values
//              assigned when the mail was created.
// * data:      Provides `data.string()` etc. for generating Jetzig Values.
// * params:    Template data for `text.zmpl` and `html.zmpl`. Inherits all response data
//              assigned in a view function and can be modified for email-specific content.
// * env:       Provides the following fields:
//              - logger:      Logger attached to the same stream as the Jetzig server.
//              - environment: Enum of `{ production, development }`.
