## ADDED Requirements

### Requirement: Production transactional email uses Resend

The system SHALL support Resend as the production mail transport via Laravel's native `resend` mailer (SPEC §9.1, §15.4). The Resend API key MUST be read from `RESEND_API_KEY` through `config/services.php`. Production deployments MUST set `MAIL_MAILER=resend` when transactional email is enabled.

#### Scenario: Resend mailer is configured

- **WHEN** the application boots with valid configuration
- **THEN** a `resend` mailer MUST exist in `config/mail.php`
- **AND** `config('services.resend.key')` MUST resolve from `RESEND_API_KEY`

#### Scenario: Local development uses safe mail default

- **WHEN** `APP_ENV` is `local` and `MAIL_MAILER` is unset
- **THEN** the default mailer MUST be `log`
- **AND** no outbound email MUST be sent to external providers

#### Scenario: Tests do not call Resend

- **WHEN** the test suite runs
- **THEN** `MAIL_MAILER` MUST be `array` (or tests MUST use `Mail::fake`)
- **AND** no live HTTP request to Resend MUST occur during CI

### Requirement: Global from address is configurable

The system SHALL read the global sender address and name from `MAIL_FROM_ADDRESS` and `MAIL_FROM_NAME` (SPEC §15.4).

#### Scenario: From address applied to outbound mail

- **WHEN** the application sends mail through the configured mailer
- **THEN** the message MUST use the configured from address and name
