lefthook.yml:4

• Markdown files (*.md) were removed from the lint glob, so README.md and other Markdown files will no longer be formatted by Biome. Consider re-adding md to the glob pattern.

      glob: "*.{js,jsx,ts,tsx,json,css}"

README.md:8

• [nitpick] Headings are inconsistent in casing. Consider using title case (e.g., ## What Is This?) for better readability and consistency.

## what is this?
