"""Offline fallback for the reference/value field moves: KiCad 10.0.6's IPC refuses PCB_FIELD updates through
kicad_silk_fields_batch (ISC_INVALID_TYPE: PCB_FIELD_T unhandled). Edits the saved board file: for every update in
apply_fields.json (field UUID -> board x/y, layer, height, stroke) rewrite that property's (at ...), (layer ...),
(effects (font (size) (thickness))) and drop (hide yes). Positions go into the footprint's local frame (inverse of the
pcb.py rotation convention); the text angle is written relative to the footprint. The board is reloaded in KiCad with
File > Revert afterwards and re-validated natively."""
