// A refused request must reject, not resolve.
//
// This helper used to end in `.then(r => r.json())`, so a 403/404/500 body resolved as an ordinary
// value and the surrounding try/catch was unreachable — every handler took the failure for success.
// Concretely: deleting a built-in layout template showed "Layout deleted" while the server had
// returned 403 and the template was still there, and a rejected platform-role change showed "Role
// updated" while the dropdown kept displaying a value the server refused (its revert lives only in
// the dead catch). The shared client in api.js has always thrown on !res.ok; these local copies did
// not. Same contract now, including the 401 session-expiry reload.
