ROUTING ONLY — everything else is done and confirmed; do not inspect,
reconcile, re-verify, or report on the outline, stackup, mounting holes, or
placement, and do not create knowledge notes.

Complete all remaining routing and copper in one pass:
- Motor loop (12 V terminal → fuse → both BTN8982TA → motor terminal): wide
  pours ≥8 mm, 15 A, with thermal via farms under both driver tabs.
- L2 solid GND plane, L3 power pours (12 V and 5 V regions), AMS1117 tab
  copper ≥600 mm² with 6 thermal vias.
- All remaining signals per the schematic nets; keep PWM (GPIO25/26) and LED
  data (GPIO5/18/19) routing away from the HX711 corner; single-point tie
  for the HX711 ground pour; IS sense resistor grounds kelvin-connected.
- ESP32 antenna keepout stays clear on all layers.

Then run DRC and fix violations, repeating until clean or until the same
violation survives two fix attempts — in that case stop and list ONLY the
unresolved violations (one line each). If DRC is clean, stop and say
"DRC clean". Do not export anything; I will export manually. No summaries
beyond that final line.
