Single frame at 375 × 760. Per-project Estimated vs Actual cost breakdown by cost code. Desktop's wide table collapses to compact stacked cards: two-column code | name header, then a 3-cell EST / ACT / Δ row. Convention per §6d: Δ = act − est, so negative is green (under budget) and positive is red (over).
Project picker is an active-only select-style chip; tapping opens a bottom-sheet list. Forward arrow (top-right) jumps to the next active project without re-opening the picker. The 3-tile summary strip mirrors desktop's KPI strip but in compact tabular-num form. Each cost-code card is two parts: the §6e two-column code | name header, then a tinted 3-cell EST / ACT / Δ row. Δ cell tints green (under) or red (over) and the value shows an explicit sign per §6d.
