Installation
Choose your framework. The registry installs the component and its runtime dependency.
Installation unavailable
The preview is public, but its installable release is still being prepared.
The registry command writes the component to src/lib/components/ui/FocusReveal.svelte and installs its dependencies.
The registry command writes the component to src/components/ui/FocusReveal.tsx and installs its dependencies.
The registry command writes the component to src/components/ui/FocusReveal.vue and installs its dependencies.
Basic usage
The shader fills its parent. Your layout decides whether that parent is a card, hero, or viewport.
