This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

- Transform and minify an inline style with Lightning CSS 1.33.0 for a Browserslist-derived Safari 12 target

Contract
- assert browserslistToTargets encodes Safari 12 as the packed target value 12 shifted by 16 bits
- assert transformStyleAttribute returns a Buffer containing declarations without selector braces
- assert minification merges four margin declarations, reduces rgb red to its keyword, and adds the Safari webkit user-select prefix while retaining the standard declaration
