Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.

+  "files": [
+    "dist/",
+    "src/",


question: Sorry to bump in here like that but I have a quick question:
Why are you publishing the files under src as well as the transpiled files under dist?
Is there some additional benefit to doing that? You should be already generating declarations.
Is this only done to allow consumers to jump to the "real" source code while developing?

Good catch! You are completely right.

To be honest, including src/ was a misjudgment made by the AI assistant I used to help configure this package. It's totally unnecessary since we already ship the compiled output and declarations in dist/.

I haven't merged this PR yet, so I will update it to remove src/ from the published files. Thanks for pointing it out!
