A Vue mixin that uses requestAnimationFrame to defer component rendering until the browser is idle, improving initial load performance. It provides a `defer` method that returns a promise resolved on the next animation frame, and a `deferUntilVisible` method using IntersectionObserver. This pattern is self-contained and can be extracted into any Vue project for progressive rendering.

A Vue component for responsive images that likely generates multiple image sources (srcset) and handles lazy loading via IntersectionObserver. It encapsulates common responsive image patterns (breakpoints, aspect ratio, blur-up placeholder) and can be reused across projects with minimal adaptation.

A Vue component that lazy-loads images using IntersectionObserver, with a blur-up placeholder effect. It is self-contained and demonstrates a clean pattern for progressive image loading that can be extracted into any Vue or Nuxt project.

The Vuex store manages global state for menu visibility, scroll position, window dimensions, and network connectivity. It provides mutations and actions for toggling the mobile menu, updating scroll state on resize, and handling online/offline events. While somewhat coupled to the app's layout, the pattern of centralizing UI state in a Vuex store is reusable as a reference for similar Nuxt projects.
