 * "Was this showcase helpful?" widget.

 * v1 storage strategy: telemetry is the source of truth for aggregate
 * analysis (`showcase.viewer.feedback.submit`). The user's vote per
 * showcase is cached in browser `UserDataService` (localStorage) purely
 * so we can suppress re-prompting on revisit — there is no backend today.
 *
 * UX: once a user votes, the buttons are replaced with a brief
 * "Thanks for the feedback!" message and then the whole widget unmounts.
 * On subsequent visits to the same showcase, the widget renders nothing.
