The custom footprints (QMA6100P, GuliKit_HallStick, BQ25185DLHR) had no model at all.

## Caveats

- EasyEDA models are community/vendor-provided and are good for enclosure design, not guaranteed
exact. Check critical dimensions (USB-C opening, button plunger, stick height) against the datasheet
or a real part before finalising a shell.
- The SK6812MINI-E is a reverse-mount part. Its body sits 0.84mm below the pad plane, and in the model
it intersects the board, because the SK6812MINI-E-012 footprint has no board cutout.
