Each cost code becomes a tappable card with the §6e two-column code | name pattern. Status icon at the left (○ pending, ● on track, ▲ over, ▼ under, ⚠ already-over). Decided cards take a tinted background so the PM sees progress at a glance. Sticky bottom bar shows count + Save-for-later + Finalize (disabled until all 16 are decided).

Tapping a "not yet" card slides up a bottom sheet (shadcn Sheet). Title is the same code | name. Three big tap targets stack vertically — each colored to its semantic tone (green / amber / blue) with a one-line description so the PM never has to remember which icon does what. ▲ Over and ▼ Under route into the existing CTC entry dialog (source picker etc.); ● On track records immediately and advances. Skip leaves the row pending; Save & next moves on without closing the session.
