/**
 * `MiniPlayer` characterization (Phase F5c).
 *
 * Per pick 4a of the v2 plan: renders + click handlers only. The
 * cross-webview bridge contract (`mini:ready` / `mini:sync` emit-listen,
 * geometry persistence) is covered separately in B-tier phase B5; jsdom
 * does not model two webviews, so an in-process test would only fake
 * what we're trying to verify.
