Data Viewer — load-more + whole-dataset filtering (parquet) · working prototype

Interactive. Funnel in any header = quick filter; ‹▽› toolbar icon = custom (SQL) filter. In a column filter: All = every value not filtered elsewhere · Visible = the current search matches · the lock keeps picks while you search · the crossed double-funnel clears the other filters. Each of All/Visible is tri-state (empty = none, check = all, dash = some). Applied filters show as an icon pipeline before the row count; click a chip to disable it (kept).
Data fabricated (RDW-style). Load-more step 500 here (prod 10,000). Click kenteken's funnel for the "first 100 of N" high-cardinality case.

Real token / primitive reference — real <venact-data-viewer> shell & real <venact-button>
The prototype's buttons/tokens mirror these real components. (The real region's grid body is empty in the sandbox — its data path needs a live backend.)
