Pure white canvas, electric cobalt #0052FF, system sans throughout in heavier weights (500–700). A deliberate departure from v9's warm linen and v10's vintage serifs — this is the Coinbase × Linear × Stripe lineage. Banking-grade clarity, no dark band anywhere. Same Sayantan, same 5-tab IA, same permission model — only the visual layer is rewritten.
5-tab IA carried over: Home · Workspace · Punch (center, cobalt pedestal) · Chats · Me. Tap the white punch circle to watch it invert to cobalt-on-white with a confident pill flying down to today's row. Status chips are solid cobalt fill with white text. Every card has a visible 1px border + ambient shadow — cards lift, never embed.
