// The drawing's mounting-side view uses the left locating hole as its datum.
// Translate that datum to the footprint origin: (11.9 mm, -12.7 mm).
// CD closes on card insertion. WP closes for a write-enabled card.
// Expose the four shell tabs as separate physical ports. They all connect to
// GND, but are too far apart to represent as one short routed pad-to-pad link.
