Mystic Library is a prompt library for managing reusable prompts in Markdown, organizing them by category, and sharing them as a static site.

It is designed for team use, with input requirements, examples, and notes for writing, development, and operational tasks.

The site UI (navigation, sidebar, footer labels) can now switch to English.

Some page contents are currently mirrored from the Japanese docs and can be translated incrementally.
