phucdt1234/Vietnav — reverse-engineered prompt

I want a tiny navigation app for Xiaomi Smart Band 10 that can be packaged as an rpk and installed with common installer apps. The watch app should be called VietNav and show the current navigation instruction from an Android companion app, so I can glance at my band while walking or riding instead of taking out my phone.

Keep the interface simple and readable on the small band screen, with the next direction, distance, and any basic status like connected or waiting for navigation. Set up the JavaScript quick app project so it builds cleanly with npm install and npm run build, and make sure the generated rpk is ready to install through Astrobox or Notify for Xiaomi and then use through Mi Fitness.

If you need details about Xiaomi Smart Band 10 quick apps, look up the current docs online.
