— serial log —

Same protocol as the old mirror app: the Arduino sends 1 to draw, the PC answers 1 when it is back on the idle screen. Also works with Space / Enter or a tap on the screen.

Everything is stored inside this browser on this PC (no internet). Images live in IndexedDB, the rest in localStorage.

Idle / start screen

Full-screen picture shown while waiting (like start.jpg in the old app). Without it, the idle text from the Look tab is shown on the background colour.

Each picture is one prize. Set the quantity under the picture — no need to duplicate files. Big images are resized to 2560 px on import.
