- Add tools/apply_scanlines.py for CRT scanline effect - Add tools/nufli_delta.py for delta encoding (base + bitmask deltas) - Delta format: 2880 byte bitmask + N byte values per screen - 40.1% size reduction vs raw NUFLI (69KB vs 115KB for 5 screens) - Base (23KB) at 000-FFF, title delta (7KB) at - - Other deltas use title as fallback (TODO: disk loading) - Update tasks.md with scanline and delta encoding documentation
