   Disabled + in-flight states

   setLoading() (plans.js / plan-forms.js) sets `disabled` and toggles
   `is-loading` on the submit button — and on the controls beside it — for as
   long as a REST write is in flight. Without these rules the class is inert,
   so a slow save is indistinguishable from a dead button.
