# scripts/launch_camelyon.sh — launch a Camelyon17 training run, detached via nohup.
#
# Usage:
#   bash scripts/launch_camelyon.sh [condition] [seed] [gpu]
#
# Defaults:
#   condition = grokking
#   seed      = 42
#   gpu       = 0
#
# Survives SSH disconnects. All artifacts in experiments/runs/<run_id>/.
