Sonner transitions break after deploy — work fine locally

Describe the bug

Hi, I’m using vue-sonner in a Nuxt 3 project. Everything works great in development — including transitions — but after deployment, the animations/transitions appear to be broken or missing.

I’ve followed the documentation steps carefully, including this related comment.

• The toast renders correctly
• But the entrance transitions are gone after deployment
• No console errors

nuxt.config.ts

css: ['~/assets/css/main.css', 'vue-sonner/style.css'],
modules: [
  'vue-sonner/nuxt',
  // other modules...
],

app.vue

<script setup lang="ts">
defineOptions({
  name: 'App',
});
</script>

<template>
  <div class="p-4">
    <NuxtPage />
    <SCToaster :visible-toasts="4" class="pointer-events-auto" />
  </div>
</template>

Local (working as expected):

local.mp4

Deployed (animations broken):

deployed.mp4

• Live demo (deployed):

Am I missing something or doing something wrong? Thanks in advance.

I have the same exact issue 😕 nuxt 3.17.5 and shadcn-nuxt 2.2.0

Exactly the same problem. Did you find a solution?
