  "description": "Board-local override for the two board-level supply nets. The shared hv-power-24v profile gives /+5V a 0.50 mm track with 0.25 mm clearance and /+3.3V 0.30 mm with 0.20 mm, sized for boards with real load. On this board both rails feed only logic and ESD arrays (under 20 mA on +5V, well under 100 mA on +3.3V) and both have to enter 0.5 mm-pitch SOT-666 and DRY6 pads, where dsn_escape_margin.py measured -0.178 mm and 0.000 mm of escape margin: the shared widths cannot reach the pins. These two classes sit one priority step above PWR_5V and PWR_3V3 so the aggregate netclass for the two root nets takes their geometry, while the shared profile's classes and patterns stay untouched and `orb-weaver-kicad-apply-netclasses --check --profile hv-power-24v` stays clean.
