Drill: Filter UI: faceted filter with active chips, counts, clear-all, URL-synced state. Target: filters persist across reload.
Interpretation: Built as Sable Instruments, a certified pre-owned test & measurement catalog (34 units, 6 categories, 9 brands, 3 conditions, stock/backorder, cal-due dates) where cross-filtering is load-bearing — brand facets genuinely zero out under category+condition constraints. Dark flat Linear/Vercel operator aesthetic with one amber accent in 5 documented roles, green strictly semantic. Fresh v2 variables: radio condition facet, numeric price range with one-sided chips, ranked counterfactual empty state with price diagnosis, mobile bottom-sheet drawer with grab handle.
Every unit ships with a fresh calibration certificate unless marked as-is. 34 units across Oakland, Austin, and Rotterdam, inspected and graded by our bench techs.
