/**
 * community blueprint · wiring seam for `@platform-modules/mail`.
 *
 * Adapter-minimalism (CLAUDE.md §4): wrap a capture adapter in createMail. In THIS blueprint mail is
 * consumed indirectly — it backs the 'email' channel of `@platform-modules/notifications` (see
 * wiring/notifications.ts), proving notifications composes ABOVE mail rather than beside it. The
 * capture array lets the composition test assert an email was actually emitted past both gates.
 *
 * (Structurally identical to saas-admin/wiring/mail.ts — another two-blueprint convergence signal.)
