mt3540: specified limits as data (metadata.characteristics, 26 rows from the datasheet)
mt3540: component.models_3d pose record per STEP (Z-up, seated z=0, pad-centre origin, identity binding)
Brief states the pinout check that actually ran (was an unconditional "Datasheet-verified pinout")
mt3540: laser-etched CAD + chip hero (factory 2.0.0 backfill)
mt3540: backfill missing artifacts (variants)
mt3540: publish the laser-etched STEP alongside the bare one
orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <te…
pin 1: carry the footprint's marker into the .lbr, the viewer and page.json (silk-marker, drawn, top-left)
mt3540: factory component page (tier=lcsc)
