Add a documentation website under website/, built from README.md and
README-Japanese.md and laid out with top-tab topics and a left sidebar (same
style as the Hayabusa docs). Designed to be hosted free on GitHub Pages.
- Pages: Overview (About, Features, Screenshots), Getting Started, Commands
(Command List, Command Usage), Resources (Companion Projects, Other
Resources, Changelog, Contributing)
- Custom landing page, theme, click-to-zoom screenshots
- Changelog synced from CHANGELOG.md at build time
- 15-language switcher via mkdocs-static-i18n: English + Japanese full content;
the other 13 localize the UI and fall back to English until translated
- .github/workflows/docs.yml builds (mkdocs --strict) + deploys to GitHub Pages
