* Bundle CSS
* For files within dep tree, find ways to combine them.
* Current logic:
* - If CSS appears across multiple pages, combine into `/_astro/common.css` bundle
* - Otherwise, combine page CSS into one request as `/_astro/[page].css` bundle
*
* This operation _should_ be relatively-safe to do in parallel with other bundling,
* assuming other bundling steps dont touch CSS. While this step does modify HTML,
* it doesnt keep anything in local memory so other processes may modify HTML too.
*
* This operation mutates the original references of the buildOutput not only for
* safety (prevents possible conflicts), but for efficiency.
