Replace 13 content fixtures with deterministic, reproducible outputs
from gen-synthetic-content.mjs:
- QR codes (PNG/SVG/AVIF): qrcode lib encoding https://snapotter.com
- Barcodes (PNG/AVIF): Code 128B encoder for SNAPOTTER-TEST-123
- OCR text (English/Japanese PNG): Sharp SVG text rendering
- PDFs (2-page/6-page): minimal PDF byte generator
- Audio (MP3 with ID3 tags, 30s WAV): ffmpeg 440Hz sine wave
- Video (1s metadata, 30s hero): ffmpeg testsrc2 + sine tone
All outputs are CC0 with no third-party IP. The generator script is
idempotent and can be re-run to reproduce identical fixtures.
- Add enable_mkldnn=False to PaddleOCR constructor to bypass PaddlePaddle
3.3+ OneDNN/PIR crash on CPU-only systems
- Add 25MP and 75% max-reduction guard to seam carving with clear error
messages instead of silent timeout/crash
- Replace barcode/QR AVIF test fixtures with actual scannable codes
(old fixtures did not contain real barcodes)
