* Build a predicate telling whether the contents of an emitted CSS file were
* inlined as `<style>` tags for this request, meaning its `<link>` can be
* dropped.
*
* The builder can only remove a link at build time when every CSS source in
* the file is inlined for a module that is always rendered. For the rest it
* records the modules that inline each source, and the answer depends on what
* the request actually rendered: a component inside `<ClientOnly>` never
* reaches `ssrContext.modules`, so its styles are only ever delivered by the
* link. (#36058)
