• Create & publish types library for the mercury global
• Create template Typescript projects for pnpm & Bun with polyfills as needed, scripts for bundling/qjs compiling & hot reloading of the bundle within your app during dev.

• For more complex/modular setups, consider extracting Refracture music's app core system into an independent library
