  "note": "Curated seed-saving guidance. Values are widely-published horticultural FACTS (isolation distances, pollination habit, population sizes) — not copied text — drawn from the sources below and cross-checked for consistency. Keyed by botanical family (defaults) with per-species/genus overrides that win. Distances in metres are conservative home-garden ranges for keeping a variety reasonably true; plant counts keep enough genetic diversity. `note` is a locale-keyed map, extensible to any language. Advisory only — adapt to local climate. A starter set, not a ceiling.",
