Lightning with Astro: Can't resolve background-image path

[djmtype]

While using Lightning with Astro, whether I reference an image from assets or public, it returns a 404. I get this message upon build:

UoptTW referenced in /Volumes/Evo/Sites/mysite/src/pages/news/index.astro?astro&type=style&index=0&lang.css didn't resolve at build time, it will remain unchanged to be resolved at runtime

Referencing it from Astro's public directory:

<style is:global>
entry-image {
  background: url(/images/image.png);
}
</style>

At build I get: background:url(UoptTW). However, no UoptTW file is ever generated. Besides, any file within Astro's public directory shouldn't be transformed.

I also tried installing the vite-plugin-lightningcss, but it didn't matter.

// astro.config.mjs

export default defineConfig({
  vite: {
    css: {
      devSourcemap: true,
      transformer: "lightningcss",
      lightningcss: {
        drafts: {
          customMedia: true,
        },
        include: Features.Nesting,
        minify: false,
        sourceMap: true,
      },
    },
    build: {
      cssMinify: "lightningcss",
    },
  },
})

BTW, if I swap out Lightning with PostCSS, I don't have this issue.
