/**
 * Alps EC11E15244G1 vertical click-encoder, from KiCad's
 * `Rotary_Encoder:RotaryEncoder_Alps_EC11E-Switch_Vertical_H20mm`. Local y is
 * negated from the .kicad_mod.
 *
 * Footprint origin is pad A; the shaft axis is at local (7.5, -2.5). A/B/C are
 * the quadrature contacts (C common), S1/S2 the push switch, MP the two frame
 * tabs — one port, two holes, on GND so the metal body is grounded.
 *
 * The MP tabs are rect pads over slots in the library, drawn here as plain
 * pills: same hole, same envelope, corners rounded off.
