[Bug?]: Official Nitro v3 static builds fail after prerendering and ignore Vite base in emitted asset URLs

Current behavior 😯

With the official Nitro v3 Vite plugin and preset: "static", the build has two independent symptoms:

1. Nitro writes .output/public/index.html, but SolidStart-generated asset URLs ignore base: "/foo/" and are root-absolute:

   <link href="/_build/assets/entry-client-....css" rel="stylesheet">
   <link href="/_build/assets/....js" rel="modulepreload">
   <script type="module" src="/_build/assets/entry-client-....js"></script>

   These are framework-generated stylesheet, modulepreload, and entry-script tags, not user-authored root-absolute URLs such as a favicon or anchor.

2. The client build, SolidStart SSR service build, and Nitro prerendering succeed. The final Nitro environment build then exits nonzero:

   [start] [nitro] Building [Nitro] (preset: `static`, compatibility: `2026-08-11`)
   [success] [nitro] Generated public .output/public
   [info] [nitro] Initializing prerenderer
   [info] [nitro] Prerendered 1 routes in 0.243 seconds
   vite v8.2.1 building nitro environment for production...
   error during build:
   rolldownOptions.input should not be an html file when building for SSR. Please specify a dedicated SSR entry.

       at buildEnvironments (.../node_modules/nitro/dist/vite.mjs:120:31)
   

The same build failure occurs when Vite is invoked directly through Node, so it is not Bun-specific.

Expected behavior 🤔

1. SolidStart-generated static asset tags should honor Vite base; with base: "/foo/", the generated URLs should begin with /foo/_build/....
2. A static build using the official Nitro v3 Vite plugin should complete with exit code 0 after prerendering and produce deployable static output.

Steps to reproduce 🕹

Steps:

1. Create a current SolidStart v2 application with src/entry-client.tsx, src/entry-server.tsx, and at least one file route.

2. Install these dependencies:

   npm install @solidjs/start@2.0.0 solid-js@1.9.14 @solidjs/router@1.0.0 @solidjs/meta@0.29.4 nitro@3.0.260610-beta vite@8.2.1

3. Use this vite.config.ts:

   import { defineConfig } from "vite";
   import { nitro } from "nitro/vite";
   import { solidStart } from "@solidjs/start/config";
   
   export default defineConfig({
     plugins: [
       solidStart({ ssr: false }),
       nitro({
         preset: "static",
         baseURL: "/foo/",
       }),
     ],
     base: "/foo/",
   });

4. Run:

   node ./node_modules/vite/bin/vite.js build

5. Observe the root-absolute framework asset URLs in .output/public/index.html, followed by the Rolldown SSR-input error and nonzero exit status.

Scope checks from the same application:

Configuration	Result
solidStart({ ssr: false }) without Nitro	succeeds
solidStart({ ssr: false }) with nitro() and the default node-server preset	succeeds
solidStart({ ssr: false }) with nitro({ preset: "static" })	fails with the SSR-input error
Same static configuration without base or baseURL	fails with the same SSR-input error
solidStart() with SSR enabled and nitro({ preset: "static" })	fails with the same SSR-input error

The static-build failure is therefore independent of SPA mode and subpath configuration. I have not established whether its cause originates in SolidStart, Nitro, or the integration. I am reporting it here because it occurs with official SolidStart v2 plus nitro/vite, and a new modern-package report was requested in #2151.

Context 🔦

I am deploying a static SolidStart application below a path prefix rather than the domain root. base: "/foo/" is required so framework-generated stylesheets and client modules resolve from the deployed location. The emitted root-absolute tags break asset loading under that prefix.

Separately, the final nonzero build exit prevents treating the generated static directory as a successful production artifact, even though prerendering has already completed.

The installed production manifest appears relevant to the first symptom because it currently produces asset paths with hard-coded root prefixes:

return join("/", viteManifestEntry.file);
output: join("/", viteManifest[entryKey].file);
href: "/" + asset;

PR #2152 appears to address that first symptom by using import.meta.env.BASE_URL.
