调研方向
Start by reading void/dist/pages/islands-plugin.mjs, especially needsIslandClientBundle() and extractCssImports(), then trace how createClientAssetTags in void/dist/routing-assets-*.mjs uses the manifest. Reproduce with the linked project using pnpm build && pnpm preview; check that production output includes the CSS link for both / and /about, including when CSS is imported through a component.

描述
Describe the bug
On island pages (*.island.tsx) and Markdown pages, CSS that is imported by a regular component (for example a shared Shell rendered by pages/layout.tsx) is applied in vite dev but missing from the production build. The rendered HTML has no <link rel="stylesheet">.
This is easy to miss because everything looks correct in dev.
Reproduction
https://github.com/Nkzn/void-islands-css-missing-repro
pnpm install
pnpm dev # / and /about have a red background
pnpm build && pnpm preview # / and /about have no stylesheet
src/Shell.tsximports./global.css;pages/layout.tsxrenders<Shell>.- In the production build,
dist/clientis not generated at all and the CSS only appears underdist/ssr/assets/.
Expected
Production output links the CSS that the page and its layouts depend on (as dev does), even when the page ships no JavaScript.
Possible cause
void/dist/pages/islands-plugin.mjsneedsIslandClientBundle()(L23) only checks the source text of*.island.*,layout.*and_*files for island imports or CSS imports written directly in those files. Transitive imports are not considered, so the islands client entry is not built here.extractCssImports()(L61) likewise only collects CSS imported directly in those files.
void/dist/routing-assets-*.mjs(createClientAssetTags, L115): when the islands client entry is not in the manifest, it returns empty asset tags, so no CSS link is emitted either.
Workaround
Import the CSS directly in pages/layout.tsx (import "../src/global.css"). Then virtual:void-islands-client is built and both pages get <link rel="stylesheet" href="/assets/islands-client-*.css">, still without any <script>.
