Logos resolve domain, then tenant, then server-wide, then the built-in, with subdomains finding their domain. GET /logo serves a data-URL image, redirects to a URL logo without fetching it, sandboxes SVG, and answers 404 when no custom logo applies. Emails embed the first PNG, JPEG or GIF logo. Logo and template writes are checked; stored templates are read at send time, always escaped, and fall back to the built-in with a build warning when they don't parse. The RSVP page is served byte for byte with a CSP and no-referrer. The sign-in and RSVP pages load the logo through an image element. MT-22's session logo follows the chain to the server-wide logo. Acceptance tests 1 to 17; test 18 written as the ignored branding_compat.
