// with INSTANCE_STATS_SECRET (404 otherwise), api/unsubscribe acts only on a
// token signed with AUTH_SECRET (one-click unsubscribe from a notification email). The uploaded logo
// (/brand/logo-*.png|jpg|webp) passes by its extension. mail/ holds the email
// logo (lib/email/layout.ts), which a mail client fetches with no session. The web app manifest is fetched by the browser without
// cookies: behind the redirect the app could not be installed.
