abse/smartwatch-flex-top-only

Three-panel flex smartwatch with two parallel R3.9 bends, all components flat-top, low-profile JST connector harnesses, split heartbeat optical windows and screw-retained PCB mounting. Modeled 39 × 50.5 × 14.5mm prototype; 100% routing, zero native DRC and shorts. Hardware qualification pending.
