 // ─── Branding ───────────────────────────────────────────────────────────────
 
+/**
+ * NOT YET WIRED end-to-end. The `/admin/branding` page persists these
+ * settings to system_settings, but the email templates in
+ * `src/lib/email/templates/` and the `<BrandedAuthShell>` component in
+ * `src/components/shared/branded-auth-shell.tsx` still hardcode the
+ * `s3.portnimara.com` logo URL and the Port Nimara color palette. A
+ * second port wired into this CRM will see Port Nimara branding in
+ * every transactional email until those consumers call
+ * `getPortBrandingConfig(portId)`. Tracked as audit finding R2-H15.
+ *
+ * To wire fully:
+ *   1. Take `branding` config as a server-side prop into
+ *      `<BrandedAuthShell>` (pass it from the page server component).
+ *   2. Refactor the email shell helper in each `templates/*.ts` module
+ *      to take `headerHtml` / `footerHtml` / `primaryColor` instead of
+ *      the inline constants.
+ *   3. In each sender, call `getPortBrandingConfig(portId)` and thread
+ *      the branding values into the template call.
