# Manual stackup description consumed by impedancefinder.board_model.load_manual_stackup().
#
# This is the primary way to supply Er/height data today: KiCad's Python API
# (verified against KiCad 10.0.4) does not expose BOARD_STACKUP to scripting,
# so Board Setup's physical stackup cannot be read back reliably. Fill this
# file in from the fabricator's stackup table instead.
#
# copper_layers: ordered top-to-bottom, using KiCad's canonical layer names.
# dielectrics: ordered top-to-bottom, one entry between each pair of adjacent
#              copper layers (len(dielectrics) == len(copper_layers) - 1).
# copper_thickness_mm: optional, defaults to 0.035mm (1oz copper) if omitted.
