Customization cannot work in [https://SAKryukov.GitHub.io/microtonal-chromatic-lattice-keyboard/playground live demo].

In the downloaded code, we only need its sub-directory “docs”, everything else can be deleted. (The weird directory name “docs” is related to the GitHub naming requirements for the content served by a product's Web site used for [https://SAKryukov.GitHub.io/microtonal-chromatic-lattice-keyboard/playground live demo]. In fact, all the production code is in this directory).
