Design the on-device interface for Astro Bot itself. Do not design or modify the iOS companion app.
Product context:
- Astro Bot is a small physical companion device with a 480×480 AMOLED touchscreen.
- The current primary experience is a full-screen animated robot face with cyan dot-matrix eyes on a near-black visor.
- The device should feel like a character first and a small operating system second.
- The face is the default home experience and should remain immersive, without permanent navigation bars or phone-like status chrome.
- This is an embedded device with limited resources, so favor simple shapes, small assets, restrained animation, and persistent reusable UI elements.
- Touch targets must be comfortable and readable on the physical 480×480 screen.
