Current behavior 馃槸
When using UnoCSS with SolidStart v2 and Vite 8, the development SSR manifest requests UnoCSS's virtual stylesheet with an ?inline query: /__uno.css?inline
Server log:
Error: Denied ID /__uno.css?inline

Expected behavior 馃
SolidStart should starts successfully without error, with either:
- resolve /__uno.css?inline as a virtual module before Vite performs filesystem ID validation; or
- provide a documented integration path for UnoCSS virtual CSS modules in development SSR.
Steps to reproduce 馃暪
Steps: Create a SolidStart v2 project using with-unocss tempalate.
pnpm create solid- Choose SolidStart + v2
- Choose
with-unocss cd project-name && pnpm installl && pnpm dev

Tracked upstream in unocss/unocss#5271 with a reproduction using the official SolidStart
with-unocsstemplate.The failure is confirmed with the current releases,
unocss@66.7.5andvite@8.2.1. The UnoCSS entry appears in the SSR module graph as:Because
fileis notnull, the condition introduced by #2293 does not run, and its published preview package still returns the same HTTP 500 withERR_DENIED_ID /__uno.css?inline.A control virtual CSS plugin using the standard Vite
\0-prefixed resolved ID works with unchanged SolidStart 2.0.0. This therefore appears to be an upstream UnoCSS virtual-module/?inlinecompatibility issue.unocss/unocss#4884 remains related, but it covers a Vite 7 production-build failure rather than this Vite 8 development SSR failure.
