+/**
+ * SyncPlayActionIcon
+ *
+ * In-button SyncPlay status indicator — drops into the player's
+ * play/pause button slot and replaces the normal play/pause/loader
+ * graphic while SyncPlay is mid-transition. Mirrors jellyfin-web's
+ * `#syncPlayIcon` element (see `showIcon()` in
+ * `jellyfin-web/src/controllers/playback/video/index.js`).
+ *
+ * Icon vocabulary (matched 1:1 with jellyfin-web's `showIcon` switch):
+ *
+ *   action          primary       secondary         pulse      spin
+ *   --------------- ------------- ----------------- ---------- ----
+ *   schedule-play   sync          play (centered)   infinite   yes
+ *   unpause         play-circle   —                 one-shot   no
+ *   pause           pause-circle  —                 one-shot   no
+ *   seek            refresh       —                 infinite   no
+ *   buffering       clock         —                 infinite   no
+ *   wait-pause      clock         pause (shifted)   infinite   no
+ *   wait-unpause    clock         play (shifted)    infinite   no
+ *
+ * Material → Ionicons mapping used here:
+ *   sync → sync, schedule → time-outline, update → refresh-outline,
+ *   play_arrow → play, pause → pause,
+ *   play_circle_outline → play-circle-outline,
+ *   pause_circle_outline → pause-circle-outline.
+ *
+ * When no SyncPlay action is active the component renders `fallback`
+ * so callers can keep the normal play/pause/loader graphic.
