# Experiment 3: Stability-Aware Initialization
# ============================================================
# Hypothesis: The network starts chaotic (lambda~2-3) because of
# standard Kaiming initialization. Using smaller weights from the
# start should produce more stable dynamics.
#
# Stable init strategy:
# - Scale down weights by 0.5
# - Use orthogonal init for linear layers (preserves gradient norm)
# - Should produce lambda closer to 0 initially
# ============================================================
