- Startup/rendering on Linux WebKit can regress when reintroducing remote fonts/CSP allowances; prefer local font assets.
- Media URL handling between project load paths should remain consistent to avoid format-specific regressions (especially WAV/MP3 behavior).
- Export pipeline changes must preserve caption modes (`none`, `sidecar`, `burn-in`) and audio enhancement behavior.
- WAV export uses `pcm_s16le` codec — only available for audio-only inputs (no video stream). Format selector conditionally shows WAV based on input file extension.
- `<select>` dropdowns need `[color-scheme:dark]` Tailwind class on Linux WebKit or the native popup renders white-on-light-gray.
- Frontend gain ranges use camelCase (`gainDb`) but the backend expects snake_case (`gain_db`). The ExportDialog maps them before sending. Any new call sites must do the same.

- **Audio normalization (#018)**: New backend endpoint `POST /audio/normalize` in `backend/routers/audio.py`. Two-pass FFmpeg `loudnorm` (measure then apply) implemented in `backend/services/audio_cleaner.py:normalize_audio()`. Falls back to single-pass if measurement fails. Frontend UI in Export panel: target selector (YouTube -14, Spotify -16, Broadcast -23, etc.) with "Normalize" button.
- **Store**: New `updateWordText(index, text)` action in `editorStore.ts` updates both `words[]` and recomputes `segments[].text`.
- **Settings panel**: New confidence threshold slider (0–1 range).
- **WAV export format**: Format selector shows "WAV (Uncompressed)" for audio-only inputs. Backend uses `pcm_s16le` codec via `_get_codec_args()` helper. Codec selection centralized in `backend/services/video_editor.py:_get_codec_args(format_hint, has_video)`.
- **Normalization moved to export**: No longer a standalone button. Integrated as `normalizeAudio` checkbox + LUFS target selector in ExportPanel. Sent as `normalize_loudness`/`normalize_target_lufs` to backend. Applied via `loudnorm` in FFmpeg audio filter chain during export.
- **Export camelCase fix**: `ExportDialog.tsx` now manually maps `gainRanges`→`gain_db` and `muteRanges`→`{start,end}` before sending to backend. Prevents Pydantic v2 field rejection.
- **color-scheme:dark**: All `<select>` elements in ExportDialog use `[color-scheme:dark]` to ensure readable native dropdown popups on Linux WebKit.
