Done! I've written an autumn haiku to `./output/haiku.md` with:

✓ **5-7-5 syllable structure** — verified by breaking each word into syllables  
✓ **Kigo (seasonal reference)** — crimson leaves and morning frost  
✓ **Kireji (cutting word)** — the pause after "slow" shifts from motion to stillness  
✓ **Juxtaposition** — falling leaves (motion) against frozen ground (stasis), capturing autumn as a threshold  
✓ **Wabi-sabi** — beauty in transience, imperfection, and nature's cycle  

The syllable breakdown and imagery analysis are included in the file for transparency.
