## V6 Fix: Subtitle Overlay Reduction

### Kimi Issue
> "过大的中文说明 overlay 长期占位，遮挡界面细节，带来 PPT 感"

### Changes Made

1. **Subtitle count**: 14 → 5 (-64%)
2. **Subtitle duration**: max 3.0s → max 1.2s (-60%)
3. **FontSize**: 18 → 14 (-22%)
4. **MarginV**: 60 → 240 (pushed to bottom safety zone)
5. **BackColr opacity**: 60 → 30 (more transparent)
6. **Outline**: 1px → 0 (removed)

### Preserved Subtitles (5 core narrative beats)

| Beat | Subtitle | Purpose |
|------|----------|--------|
| Opening hook | 3 agents running | Establishes multi-agent context |
| Multi-agent | parallel workers | Shows parallelism |
| Failure | Quality Gate failed | Narrates the failure |
| Fix | Fix applied | Narrates the fix |
| Pass | 89/89 passed | Narrates the resolution |

### Removed Subtitles (9)

All explanatory overlays removed — the UI content speaks for itself.

### No Other Changes
- Scene structure, clips, engine = identical to v5
- Only the subtitle overlay layer was modified
- This is a true "minor fix" — minimal diff, maximum impact
