// Minimal permissive Express-ish request/response types for the migrated routes
// and middleware. @types/express is not installed and the handlers are dynamic
// (req.user is added by requireAuth, req.body/query are user input), so these
// carry an index signature — typed enough for `.json()/.status()` chaining and
// the common fields, permissive everywhere else. Swap for @types/express +
// declaration-merged `user` if the routes ever warrant full typing.
