* Minor updates only * Added explicit radix parameter (10) to all Number.parseInt() calls throughout the codebase (new lint rule) * Updated several @ts-ignore comments to @ts-expect-error for better TypeScript practices (new lint rule) * Removed unnecessary @ts-ignore comments in some mode files (ditto) * Used "none return" based arrow functions for some map stuff * Replaced a `map()` call that didn't return anything to a for() loop * Fixed up some cypress stuff, noting work for the future
