Variable: FULLSCREEN_BUTTON_HTML

const FULLSCREEN_BUTTON_HTML: string

A hoverable "view fullscreen" button, overlaid on a demo/example frame the same way VitePress's own code-block "copy" button reveals on hover. Purely markup — wire a delegated click handler in your host page (button.closest(...).querySelector("iframe")?.requestFullscreen(); see the pantoken docs theme for the reference wiring) and style the reveal-on-hover with @pantoken/demo/demo.css.
