+# Verifies the library builds and its unit tests pass against every supported
+# Angular major. Instead of scaffolding a fresh workspace per version, we keep
+# the committed workspace (angular.json, tsconfig*, jest config) and just swap
+# the installed Angular toolchain. The only per-version knowledge that lives
+# here is the compatibility map below (Node / TypeScript / zone.js /
+# jest-preset-angular), which is intrinsic to Angular's own support policy.
