• Rive CLI: I built the prototype and MVP with the CLI (scene, Luau scripting, data binding, verification and screenshot tests), going back and forth with the Rive Editor for layout and visual polish.
• GPU Canvas: almost every effect is a WGSL shader running inside Rive: the ritual circle and its sparks, the capture bursts, the summoning portal, fog and candle light, fireflies and paper-cut confetti.
