Done! I've written the haiku to `./output/haiku.md`. The poem follows the traditional 5-7-5 syllable structure with:

- **Kigo:** "Crimson leaves" and seasonal imagery of autumn
- **Kireji:** The paradox of silence "speaking" — creating juxtaposition between sound and stillness
- **Wabi-sabi:** The beauty found in the bare branch stripped of leaves, emphasizing transience and incompleteness

Each syllable was carefully counted and verified before finalizing the text.
