1. change function comments to the minimal [tsdoc](https://tsdoc.org/) style. This has the benefit of making editors show the doc string in tooltips when the function is hovered: <img width="521" height="110" alt="image" src="https://github.com/user-attachments/assets/b966f4f1-8239-433a-a456-5bd5c05d69ef" /> 2. disable eslint `multiline-comment-style` as it conflicts with tsdoc. --------- Signed-off-by: silverwind <me@silverwind.io>
