// XL-3216WWC / C965830: warm white, 2800–3400 K, 20 mA ABSOLUTE MAX.
// Use 15 mA nominal or less, and verify thermal derating in the enclosure.
// Datasheet p8: physical pin1 = cathode, pin2 = anode; recommended land pattern
// is 0.8 x 1.5 mm pads separated by a 1.7 mm gap. Override the much larger
// catalog lands while preserving supplier identity and package model.

// This modest-output LED must pass illuminance/colour and camera-glare testing.
