/** Jiangsu Huawha MLT-5020 5.0 x 5.0 x 2.0 mm SMD electromagnetic buzzer (JLC C94598, 106k in stock):
 * 2-4 V (3 V rated), 100 mA max, resonant 4 kHz, 75 dB at 10 cm. Magnetic transducer = coil, so it
 * needs a square-wave drive near 4 kHz (nRF9151 PWM) through a low-side MOSFET and a flyback diode.
 * Land pattern and numbering = the JLC/EasyEDA library footprint, which matches the Huawha datasheet dimension
 * drawing (top view): pad 1 "+" bottom-left, pad 2 "-" bottom-right, pad 3 mechanical tab (NC) top-left, the
 * top-right corner is the body's chamfer and has no land. 1.7 x 0.7 mm lands on a 4.6 x 3.5 mm grid. Numbering
 * matches JLC's so the pick-and-place rotation check works. (Until 2026-09-24 the lands were numbered like a dfn4,
 * which put "+" on the mechanical tab: the buzzer would have been silent.) */
