Problem and behavior
Native import loading alone does not give Code OSS a browser-shaped CSSOM. This cumulative stack top adds
CSSImportRule, live childCSSStyleSheetownership, nested relative imports, media/layer/supports reflection, live child declaration/rule mutation, flattened native publication with imported URL rebasing, and deletion/detach semantics.Regression coverage includes the runtime compatibility adapter plus a browser/native contract with linked, nested, qualified, mutable, and deleted imports.
Stack
Merge the provider first, retarget this PR to main, then merge this cumulative top.
Validation debt
Per the implementation-throughput directive, the included gates were authored but not run. Build, native/browser/WPT, performance, memory, lifecycle, package, and CI validation remain required before release promotion.
Closes #482
Closes #480
