/settings/calendar now shows the Google Calendar connection: "Connect
Google Calendar" (a full-page navigation to the connect endpoint) when not
connected; "Connected · {calendar}" in teal-800 with a picker of the
writable calendars, saved on choice, and Disconnect behind a confirmation
when connected; and a grape banner with Reconnect, no picker, when Google
has refused the grant. The settings list's Google Calendar row reads the
same connection instead of the placeholder endpoint.
The plan screens' "Looks good — push to Calendar" and "Push to Calendar"
buttons now POST /api/v1/plans/{weekStart}/push-calendar, showing progress
and storing the synced plan the server answers with. Failures only the
settings can fix (google_reconnect_required, no_calendar, not_connected,
calendar_unavailable) link to /settings/calendar; plan_changed reads the
plan again; any other failure offers Retry. The mobile Draft board shows
the existing sync status line under its push button.
