The handheld's operating shell, built to run in a browser before the hardware exists
TurtleOS is the launcher and shell that Turtle boots into: a window manager, an app model, and a persistent local store, assembled from a single token file and a vendored icon set so the whole look can change from one place. It runs in a browser today, which means the software side of the handheld can be designed, used, and corrected long before a board comes back from fabrication.
Runs in a browser, so the handheld's software is usable before the hardware is finished
One token file drives the entire shell, launcher, and app chrome
Per-app modules over a single IndexedDB store, no server and no account
