Detailed Description

Apply repeatable hardware profiles through v4l2-ctl.

The profile values target the USB camera validated for OpenRoadCode. Although the device advertises exposure_time_absolute, it reports that control inactive and rejects writes while streaming. Low-light mode therefore leaves exposure automatic and uses supported gain, gamma, and backlight controls instead.
