This app is ZAMA's BSD 3-Clause Clear demo. The license requires its notices to survive redistribution, and a rebrand had replaced every one of them with ours: the LICENSE text, 66 source headers and the app's copyright string. They are back, each with our line beside it for our changes. Co-authored-by: Hanzo Dev <[email protected]>
