/**
 * saas-admin blueprint · wiring seam for `@platform-modules/mail`.
 *
 * Adapter-minimalism (CLAUDE.md §4): wrap a capture adapter in createMail. The host injects a real
 * provider adapter (resend/ses/…); the blueprint proves the seam — createMail validates the message
 * at the trust boundary (malformed addresses never reach the adapter) then delegates to send. The
 * capture array lets the composition test assert a notification was actually emitted past the gate.
