## Score

`score = 0.35·classification + 0.25·metrics + 0.20·traits + 0.10·useCase + 0.05·language + 0.05·variable`; every axis in [0, 1]. A family gate runs first: specialist families (blackletter, script, glyphic, stencil, monospace, pixel) only list same-family fonts; elsewhere a cross-family mismatch is capped at 0.2. Curated picks are listed first, then pure formula; ties break on popularity, then slug.
