Budget gate
Every lamp in the index on one price line. Drag a budget and see it treated as a suggestion, or as a gate.
Every lamp in the Vessim index sits on one price axis at its lowest price. Drag the budget and switch between a suggestion, where dearer lamps only dim, and a gate, where they are gone, as Vessim treats a budget; the suggestion is a behaviour, not a named shop. On October 23, 2026: 12 lamps, $6.42 to $74.31.
