Drill: Filter UI: faceted filter with active chips, counts, clear-all, URL-synced state. Target: filters persist across reload.
Interpretation: Built as a seed-bank accession catalog (35 accessions, 5 crop groups, 6 origins, 3 conservation statuses) where cross-filtering genuinely zeroes out. Light cool-neutral archival theme, one conservation-green accent contracted to selection semantics, status pills ink-neutral with shape glyphs. Mixed facet grammars: 3 checkbox facets + 1 radio + 1 numeric germination range with one-sided chips; bottom-sheet drawer and purpose-built labeled result cards on mobile.
Open-pollinated and conservation lines held at the Whin & Hollow repository. Germination tested within the last 18 months; quantities are viable-seed grams remaining in active store.
