Tuya Miniapp for Lighting Control

I want a straightforward Tuya miniapp whose single purpose is to let me control my smart-lighting devices from within the Tuya ecosystem. The focus is purely on lighting—no thermostats or cameras—so the code and UI can stay lean and fast.

I need a custom Tuya Smart MiniPanel / MiniApp built for my Tuya Developer account. Key features required:
5-Channel Spectrum Control: Sliders for Red, Green, Blue, Cool White, and Warm White.
Smooth Gradual Transitions (Fade Engine): The system must smoothly transition light intensity and color temperature over set time intervals (e.g., 30–60 minute sunrise/sunset ramps) rather than abrupt stepped jumps.
24-Hour Programmable Lighting Curve: A visual daily schedule editor (Sunrise, Noon Peak, Sunset, Night Moonlight).
Biotope Weather Presets: Buttons for quick modes (Amazon Daylight, Deep Sea Blue, Tropical Thunderstorm).
