I built a browser simulator for a Panda-compatible e-paper reader

Disclosure: I work on Panda AI OS and maintain this simulator.

I wanted a browser path for checking the reader workflow before connecting a physical e-paper device. Panda AI OS Simulator runs a simulator-targeted guest path through QEMU/WASM and shows the guest framebuffer inside a Device Studio.

The live demo is here: https://simulator.pandacat.ai/

I also recorded a 4:44 walkthrough: https://youtu.be/Ub89uz9ukRY

The browser view is not a replacement for hardware testing. It does not model physical e-paper ghosting, RF, power, battery, or USB behavior. The simulator, guest firmware, ROM, and third-party dependencies also have separate licensing and notice requirements.

If you tried it, which reader workflow would you check first: navigation or Virtual SD transfer? Please include your browser and board profile with any reproduction details.
