# Options:
# --layers LAYER,LAYER,... KiCad layer names to export (default: F.Cu)
# --invert LAYER,LAYER,... Layers to invert (comma-separated, e.g. F.Cu,B.Mask)
# --mirror LAYER,LAYER,... Layers to mirror (comma-separated, e.g. F.Cu,F.Mask)
# --invert LAYER,LAYER,... Layers to invert (comma-separated)
# --mirror LAYER,LAYER,... Layers to mirror (comma-separated)
# --exposure SECONDS Exposure time in seconds (default: 60)
# --dummy FILE Dummy .pm4n template (default: Dummy.pm4n beside this script)
# --out DIR Output directory (default: ./output)
# --dpmm N Render resolution in dots/mm (default: native 58.824)
# --pos X,Y Board position on LCD in mm (default: centred)
# --verbose Print detailed progress
# -h, --help Show this help
#
# Example:
# ./export_for_msla.sh --invert F.Cu,B.Mask --mirror F.Cu,F.Mask panel/Flow_Controller_Panel.kicad_pcb
# Normal output: one output filepath per layer.
# Verbose output: full progress from KiCad and the converter.
#
# Layer name → Gerber filename mapping (KiCad default):
# F.Cu → <board>-F_Cu.gbr
# B.Cu → <board>-B_Cu.gbr
# F.Mask → <board>-F_Mask.gbr
# B.Mask → <board>-B_Mask.gbr
# F.SilkS → <board>-F_Silkscreen.gbr
# (etc.)
# Example:
# ./export_for_msla.sh --invert F.Cu,B.Mask --mirror F.Cu,F.Mask panel/board.kicad_pcb
#
# KiCad layer name → Gerber filename stem:
# F.Cu → F_Cu B.Cu → B_Cu
# F.Mask → F_Mask B.Mask → B_Mask
# F.SilkS → F_Silkscreen B.SilkS → B_Silkscreen
# F.Paste → F_Paste B.Paste → B_Paste
# Edge.Cuts → Edge_Cuts
# Front → Front Back → Back
