Detailed Description

RGB LED component — state holder with 8-bit color depth.

RgbLed stores per-channel duty cycle (0-255). The output backend (SoftPwm for BCM, or GPIO for bang-bang) reads state via state().

The 3-bit Color enum provides the 8 RGB cube corners at full brightness. For intermediate colors, use set_rgb().

Usage: sbl::components::display::RgbLed led; led.set_color(sbl::components::display::Color::Red); led.set_rgb(128, 0, 255); // purple at half red auto s = led.state(); // {128, 0, 255}
