Your gut is right for most apps. localStorage is readable by any script on the page, so one XSS hole means stolen sessions. HttpOnly cookies are not. Supabase's @supabase/ssr and Auth.js both do cookies for you; use the default instead of inventing the storage layer.

The one case for tokens in JS: a pure SPA calling a third-party API with short-lived tokens. That is not your app.
