chess-sim/code/sim/phase2_baseline.toml

# Baseline profile: the simplest scene, to get reliable closed-loop success before
# adding variety back one change at a time. Merged over phase2_config.toml when
# PHASE2_PROFILE=baseline is set (only the keys listed here change).
#
# Fixed: the nominal board (square to the robot, which plays black, flush against the
# deck), reference piece set, tray on the right, table, lighting (the scene's window
# and ceiling lamps), an overhead camera like the owner's (65 cm up,
# straight down, 44 degree lens), no clutter. Black and white pieces, white arm. Outlined markers.
# Ten fixed opening moves from the start position. Sharper video (CRF 18, full
# chroma) so the markers survive encoding.
