* feat: add YouTube design concept extractor tool
Extracts transcript, metadata, and keyframes from YouTube videos
into a structured markdown reference document for agent consumption.
Supports interval-based frame capture, scene-change detection, and
chapter-aware transcript grouping.

* feat: add OCR and color palette extraction to yt-design-extractor
- Add --ocr flag with Tesseract (fast) or EasyOCR (stylized text) engines
- Add --colors flag for dominant color palette extraction via ColorThief
- Add --full convenience flag to enable all extraction features
- Include OCR text alongside each frame in markdown output
- Add Visual Text Index section for searchable on-screen text
- Export ocr-results.json and color-palette.json for reuse
- Run OCR in parallel with ThreadPoolExecutor for performance

* feat: add requirements.txt and Makefile for yt-design-extractor
- requirements.txt with core and optional dependencies
- Makefile with install, deps check, and run targets
- Support for make run-full, run-ocr, run-transcript variants
- Cross-platform install-ocr target (apt/brew/dnf)

* chore: move Makefile to project root for easier access
Now `make install-full` works from anywhere in the project.
https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV
* fix: make easyocr truly optional, fix install targets
- Remove easyocr from install-full (requires PyTorch, causes conflicts)
- Add separate install-easyocr target with CPU PyTorch from official index
- Update requirements.txt with clear instructions for optional easyocr
- Improve make deps output with clearer status messages
https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV
* fix: harden error handling and fix silent failures in yt-design-extractor
- Check ffmpeg return codes instead of silently producing 0 frames
- Add upfront shutil.which() checks for yt-dlp and ffmpeg
- Narrow broad except Exception catches (transcript, OCR, color)
- Log OCR errors instead of embedding error strings in output data
- Handle subprocess.TimeoutExpired on all subprocess calls
- Wrap video processing in try/finally for reliable cleanup
- Error on missing easyocr when explicitly requested (no silent fallback)
- Fix docstrings: 720p fallback, parallel OCR, chunk duration, deps
- Split pytesseract/Pillow imports for clearer missing-dep messages
- Add run-transcript to Makefile .PHONY and help target
- Fix variable shadowing in round_color (step -> bucket_size)
- Handle json.JSONDecodeError from yt-dlp metadata
- Format with ruff
