   DESIGN & BUILD (.sk-db) — "bàn vẽ kỹ thuật / drafting board": giấy kem #f5f4f1 lưới milimet, nét đen mảnh,
   đường kích thước + ghi chú cam, khung tên bản vẽ, dấu DRAFT/APPROVED, số kích thước tabular-nums.
   Nhịp: giấy sáng ↔ bảng đen (.db-dk). Chuyển động: nét tự vẽ (stroke-dashoffset), PLAN → ELEVATION → 3D.
   Hệ màu: cam / đen / trắng (+ xám, cam nhạt, giấy). Một font Be Vietnam Pro.
