+## Current Milestone: v4.0 Figma Design Parity
+
+**Goal:** Bring every product surface to match the Figma design — new task views (grid + roadmap), calendar rework, navigation refresh, and tablo list revamp.

+- Tablo list: project card revamp + card/list view toggle
+- Tasks: restyle kanban + new grid view + new roadmap view
+- Calendar: restyle `/planning` as Google Calendar-style (month/week/day navigation, proper event blocks)
+- Tablo detail view restyled to match Figma
+
