@@ -43,4 +43,11 @@ Scope:
 
 Implemented `subtitleStyle.autoPauseVideoOnHover` with default `true`, wired through config defaults/resolution/types, renderer state/style, and mouse hover handlers. Added playback pause-state IPC (`getPlaybackPaused`) to avoid false resume when media was already paused. Added renderer hover behavior tests (including race/cancel case) and config/resolve tests. Updated config examples and docs (`README`, usage, shortcuts, mining workflow, configuration) to document default hover pause/resume behavior and disable path.
 
+Follow-up adjustments (2026-03-04):
+
+- Hover pause now resumes immediately when leaving subtitle text (no Yomitan-popup hover retention).
+- Added `subtitleStyle.autoPauseVideoOnYomitanPopup` (default `false`) to optionally keep playback paused while Yomitan popup is open, with auto-resume on close only when SubMiner initiated the popup pause.
+- Yomitan popup control keybinds added while popup is open: `J/K` scroll, `M` mine, `P` audio play, `[` previous audio variant, `]` next audio variant (within selected source).
+- Extension copy drift detection widened so popup runtime changes are reliably re-copied on launch (`popup.js`, `popup-main.js`, `display.js`, `display-audio.js`).

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Remove Plausible analytics integration from docs theme and dependency graph. Keep docs build/runtime analytics-free.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Docs theme no longer imports or initializes Plausible tracker.
+- [x] #2 `@plausible-analytics/tracker` removed from dependencies and lockfile.
+- [x] #3 Docs analytics test reflects absence of Plausible wiring.
+
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Deleted Plausible runtime wiring from VitePress theme, removed tracker package via `bun remove`, and updated docs test to assert no Plausible integration remains.

+By default, hovering over subtitle text pauses mpv playback. Playback resumes as soon as the cursor leaves subtitle text. Set `subtitleStyle.autoPauseVideoOnHover` to `false` to disable this behavior.
+
+If you want playback to stay paused while a Yomitan popup is open, set `subtitleStyle.autoPauseVideoOnYomitanPopup` to `true`. When enabled, SubMiner auto-resumes on popup close only if SubMiner paused playback for that popup.
