 ## Acceptance Criteria
 <!-- AC:BEGIN -->
-- [ ] #1 Document current overlap/input conflict behavior when both overlays are enabled.
-- [ ] #2 Prototype or design approach for content-bounded overlay window sizing for visible and invisible overlays.
-- [ ] #3 Evaluate interaction model and technical constraints for a dedicated top secondary-subtitle bar independent from overlay visibility.
-- [ ] #4 Define implementation plan with tradeoffs, edge cases (line wrapping, long lines, resize, multi-monitor, mpv style sync), and recommended path forward.

 <!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Baseline current behavior
+- Trace current visible/invisible overlay window creation and sizing behavior in main process and renderer paths.
+- Document why enabling both overlays causes overlap and input/hover conflict.
+
+2. Design content-bounded overlay sizing
+- Evaluate measurement sources (renderer DOM bounds vs main process approximations).
+- Define sizing algorithm (content bounds + padding + min/max + screen clamping) and update triggers.
+- Identify required IPC contracts and ownership boundaries.
+
+3. Design decoupled top secondary-subtitle bar
+- Define a dedicated top region/window independent from primary subtitle visibility.
+- Specify behavior for secondary subtitle display modes (hover/always/never) and pointer-event policy.
+
+4. Recommend phased implementation
+- Produce concrete file-level rollout steps, risks, edge cases (wrapping, long lines, resize, multi-monitor, style sync), and validation approach.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Completed code-path investigation across overlay window creation/sizing, visibility gating, IPC mouse passthrough, and renderer interaction layers.
+
+Documented current conflict mechanism and architecture limitation: shared fullscreen bounds ownership across both overlay windows blocks safe simultaneous activation.
+
+Proposed renderer-driven content-bounds IPC model, per-window bounds ownership, and a dedicated secondary top-bar window with mode-specific behavior.
+
+Included phased implementation plan with risks and edge-case handling in docs/overlay-window-sizing-investigation.md.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Completed investigation and design for dynamic overlay window sizing and decoupled secondary subtitle rendering.
+
+What changed:
+- Added `docs/overlay-window-sizing-investigation.md` with a code-referenced analysis of current overlay behavior.
+- Documented why overlap/input conflicts emerge under simultaneous overlay activation: both windows are full-size and currently share bounds ownership semantics.
+- Designed a content-bounded sizing approach based on renderer-measured DOM bounds reported to main via IPC, with clamping, jitter guards, and fallback behavior.
+- Evaluated top-bar decoupling options and recommended a dedicated secondary overlay window for independent lifecycle, z-order, and pointer policy.
+- Defined a phased file-level implementation path and explicit edge-case handling (wrapping/long lines, resize churn, multi-monitor transitions, mpv style/render sync).
+
+Validation:
+- Investigation validated by tracing current runtime/services/renderer code paths; no runtime behavior changes were applied in this task.
+- No automated tests were run because this task produced design documentation only (no executable code changes).
