# Similarity features per mode (ARCHITECTURE §7) and Country DNA dimensions.
#
# Each feature: indicator (registry slug), transform: none|log|log1p, weight (default 1).
# Optional `per: <slug>` divides the indicator by another one (e.g. net migration per 1,000 people, scale multiplies).
# Countries need ≥ 70 % of a mode's features (by weight) to be scored; z-scores are computed across countries from the
# `latest` table; distance = weighted Euclidean over shared features, rescaled to the full weight; score = 100·exp(−d/d0)
# where d0 = median pairwise distance of the mode. Top 12 peers are stored with per-feature contributions.
