Detailed Description

RGB LED output convenience functions.

Composes RgbLed state with a driver backend in a single call. Two overloads:

• GPIO backend: bang-bang write (on/off via GpioHandle)
• SoftPwm backend: 8-bit duty cycle via channel indices

Usage: // GPIO (bang-bang) sbl::led::write<sbl::driver::Gpio>(led, handle_r, handle_g, handle_b);

// SoftPwm (8-bit BCM) sbl::led::write<sbl::driver::SoftPwm>(led, ch_r, ch_g, ch_b);
