Reproduction

Minimal reproduction steps:

1. Create a Nuxt 4 project.
2. Add the drawer component from the current shadcn-vue template.
3. Keep the generated Drawer.vue as-is:

<script lang="ts" setup>
import type { DrawerRootEmits, DrawerRootProps } from "vaul-vue"
import { useForwardPropsEmits } from "reka-ui"
import { DrawerRoot } from "vaul-vue"

const props = withDefaults(defineProps<DrawerRootProps>(), {
  shouldScaleBackground: true,
})

const emits = defineEmits<DrawerRootEmits>()

const forwarded = useForwardPropsEmits(props, emits)
</script>

<template>
  <DrawerRoot
    v-slot="slotProps"
    data-slot="drawer"
    v-bind="forwarded"
  >
    <slot v-bind="slotProps" />
  </DrawerRoot>
</template>

4. Run nuxt typecheck (or vue-tsc --noEmit).

Current upstream template:

• https://github.com/unovue/shadcn-vue/blob/dev/apps/v4/registry/bases/reka/ui/drawer/Drawer.vue

Describe the bug

The current Drawer.vue template can fail type-checking in Nuxt 4 consumers with:

error TS2698: Spread types may only be created from object types.

The error is reported at v-bind="forwarded".

In our consumer verification, this happened after updating to a package generated from the current shadcn-vue drawer template. Restoring the older cast fixes the problem:

const forwarded = useForwardPropsEmits(props, emits) as ComputedRef<Record<string, unknown>>

This looks like a type incompatibility around vaul-vue + reka-ui + Vue/Nuxt type-checking, but the generated component currently ships without the cast.

Expected behavior:

• The generated drawer component should type-check in Nuxt 4 consumers without requiring a downstream patch.

Actual behavior:

• Consumers may need to patch the generated Drawer.vue manually to avoid TS2698.
