Awesome, I've been playing in the ebook space myself, will check it out. Particularly interested in digging into the code too see how you skip headers, footnotes, etc.

Just one quick note as I ran into this when setting it up:

   ╰─▶ Because the requested Python version (>=3.8) does not satisfy Python>=3.10,<3.13 and kokoro==0.9.4 depends on Python>=3.10,<3.13, we can conclude that kokoro==0.9.4 cannot be used.

Note I definitely disregarded your instructions and used `uv` to setup the project. Still, it seems like changing the `pyproject.toml` to `requires-python = ">=3.10"` would be good considering kokoro's Python version support.
