Preview Driven Development

" summary

Argues that Jetpack Compose Previews become a fast development surface by isolating features into previewable modules, using fake repositories and split modules (e.g. network vs network-live) so previews only pull lightweight interfaces not heavy runtime libs. Shows a weather demo app that deploys previews to device and a playground app that runs the whole UI against fakes; previews work and speed up iteration. Simulates slow builds (≈8m45s) to justify separation.
