Reactive UI Toolkit — documentation site

The family landing page at reactiveuitoolkit.info, plus each engine leg's documentation mounted underneath it.

Path	Source	How it gets here
/	index.html in this repo	hand-maintained
/godot/	ruitk-godot	pushed by that repo's Publish workflow
/unity/	ruitk-unity	pushed by that repo's Publish workflow
/unreal/	ruitk-unreal	pushed by that repo's Publish workflow

Do not hand-edit the engine folders — they are build output and are overwritten on every publish. Edit docs in the leg repo they came from.

The landing page uses only relative paths, so it renders correctly whether served from the apex domain or from a subpath.

Notes

• GitHub Pages serves this repo's default branch at root.
• Do not add branch protection here: the leg repos push directly to main.
• .nojekyll keeps Jekyll from eating the _-prefixed asset folders in the docs builds.
