This is a static GitHub Pages deployment of the FUI-AS demo app. The built assets (WASM, JS, HTML) are served directly from the repo root.

What's here

• Advanced controls — text inputs, dropdowns, checkboxes, radio buttons, sliders, progress bars, drag-and-drop reorder, context menus, dialogs
• Templated controls — custom presenter/template examples
• Text & fonts — live text wrapping, font selection, visibility toggles, scrollbar visibility
• Dark & light themes — system theme interpolation with live toggle
