recommendedCrossSection now satisfies two criteria and takes whichever demands more copper: the voltage-drop budget, and an ampacity at least as high as the fuse protecting the circuit (ABYC E-11: the OCP rating must not exceed the conductor's ampacity). Ampacity comes from ABYC E-11 Table 6A for AWG and ISO 13297 Table A1 for mm², both 105 °C. Before this, a 40 A load over 0.5 m was sized 1.5 mm² / AWG 16 next to a 50 A fuse: a cable the fuse can never protect. Long runs stay voltage-drop driven and unchanged. The drop budget is now stored per system (3 / 5 / 10 %) and editable in the system editor, with a global default in Settings that the standalone calculator uses and new systems inherit. Cross-sections are derived, never entered by the user, so LoadCableSync re-derives them when a system opens and when its budget changes. Library loads are computed instead of being stored as a 1.0 mm² placeholder. LoadConfigurationStatus therefore reports only what the user can actually fix: missing length or current. Also removes the dead cable.pro.* strings and folds three copies of the mm²-to-AWG conversion into ElectricalCalculations.nearestAWG.
