INTERACTIVE (PRESCRIPTIVE — Leads-board evolution). The Compact chip toggles the whole board between full Stacklight cards and 56px compact cards (each card carries both canonical instances; a board-level class flips visibility — no reload). Click a column's eye to collapse it in place to its .sb-leadrail; click the rail to bring it back — multiple columns can collapse. Columns scroll vertically inside their tint containers. Board opens filtered to leads CREATED TODAY; untouched red-02 cards sort first in Fresh (deal created → zero outbound since; clears on first outbound touch). The "Leads" tab is a design-ahead rename — the shared topbar atom keeps "Desk" until the app ships it.
