Follows two breaking firmware wire changes (CCS-HA-61). Firmware #116 removed the origin byte and the manual lockout byte, so the codecs, lockout attributes, ORIGIN constants and bench transcription are gone, and Spec section citations are renumbered (old 9.x shifts down one). Firmware #107 turns the CCT light into a colour light: CMD_COLOUR / STATE_COLOUR, presented as PK_COLOUR. The HA light now drives brightness, colour temperature and HS colour through CMD_COLOUR, and on/off through CMD_SWITCH. Asking for a colour temperature sends saturation 0, so the light is white at that temperature.

The shared vectors are taken from firmware main, which now includes #107.

Tested: ruff, mypy and the full suite pass locally (1314 passed, 3 skipped).

Offsets in catalogue.py and frame_bench match the kitchen-cct spec. Findings below.

custom_components/campercan/light.py Outdated

					"""Asking for a colour temperature also takes the light out of any hue it was in."""

					changes: dict[str, int] = {}

					if ATTR_BRIGHTNESS in kwargs:

						changes["brightness"] = round(kwargs[ATTR_BRIGHTNESS] * 100 / FULL_BRIGHTNESS)

Brightness 1 to 2 of 255 rounds to 0 %, so a dim request on a colour light sends brightness 0. Clamp to at least 1 when a brightness was asked for. No test covers the low end.
