//! A stylesheet imported `?inline` is a module of its own that never
//! self-accepts, as Vite's css-analysis marks it: its importer holds the
//! text, so an edit reaches the importer (here the entry, so the page
//! reloads, as under Vite). A sheet imported plainly still swaps its
//! `<style>` in place.
