## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Preload exposes a typed API for reporting overlay content bounds with layer metadata.
- [ ] #2 Main-process IPC handler validates payload shape/range and stores latest measurement per layer.
- [ ] #3 Renderer emits measurement updates on subtitle, mode, style, and render-metric changes with throttling/debounce.
- [ ] #4 No crashes or unbounded logging when measurements are missing/empty/invalid; fallback behavior is explicit.

## Implementation Notes
<!-- SECTION:NOTES:BEGIN -->
Added a typed `OverlayContentMeasurement` IPC contract exposed in preload and Electron API typings. Implemented a main-process measurement store with strict payload validation and rate-limited warning logs for invalid reports. Added renderer-side debounced measurement reporting that emits updates on subtitle content/mode/style/render-metric and resize changes, explicitly sending `contentRect: null` when no measured content exists to signal fallback behavior.
Added unit coverage for measurement validation and store behavior.
<!-- SECTION:NOTES:END -->
## Final Summary
<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Implemented renderer-to-main measurement reporting for overlay content bounds with per-layer metadata. Main now validates and stores latest measurements per layer safely, renderer emits debounced updates on relevant state changes, and invalid/missing payload handling is explicit and non-spammy.
