/**
 * PentairLightAccessory – HomeKit accessory for a Pentair IntelliBrite color light.
 *
 * HomeKit service: Lightbulb with the following characteristics:
 *  - On         → light on / off   (cloud field: lse)
 *  - Hue        → 0–360°           (cloud field: lco, Pentair color index)
 *  - Saturation → 0–100 %          (used to detect "white" mode: < 20% → White)
 *
 * Hue → Pentair color index mapping:
 *  0–20 or 340–360 → Red      (4)
 *  21–60           → Party    (5)   orange/warm range
 *  61–150          → Green    (3)

 *  261–290         → Romance  (6)   purple
 *  291–339         → Magenta  (1)
 *  Saturation < 20%→ White    (0)   (overrides hue)
 *
 * Cloud API payload fields:
 *  lse  – light on/off ("1" / "0")
 *  lco  – color index as string
