"""Convert the Ungok P1 working params.json into the app schema `pier-T/1`.

The legacy build scripts kept some values as code constants. They are moved into params here, each with
its source, so that the app builders contain no pier-specific numbers:
  rebar_marks            <- MARK / MARK_DIA tables of the legacy build scripts (D3 schedule reading)
  footing_rebar.a_y/a_x  <- D3 B1 a 7.600 / B5 a 9.150
  coping_rebar.soffit_arc_centre <- rounded right soffit-arc centre used by the legacy coping build
  coping_rebar.stirrups.top_right/top_left <- band thresholds that were encoded in key names
  sole_plates.h3         <- D2 ELEVATION TABLE h3
  display                <- layer colours, diameter palette, hidden objects (user decisions)
usage: python migrate_legacy_params.py <legacy params.json> <out params.json>
