A pixel-perfect iPad Pro landscape mockup of a kanban project management board in flat design light mode. The board has five columns: "Backlog", "In Design", "In Dev", "Review", and "Done". Each column header is in 14px semibold with a small count badge (e.g. "In Dev · 6"). Task cards are white with 8dp corner radius and a subtle 1px border in light gray. Each card shows a coloured left-border stripe (team color), task title in 13px medium, an avatar row (2-3 circular face placeholders), and a due date chip in light gray. Cards can have a small colored label chip ("UI", "Backend", "Bug") at the top. The "In Dev" column is slightly highlighted with a pale blue column background. A top toolbar shows the board name "Helion Q3 Roadmap", filter controls, and a teal "+ Add Task" button. The sidebar on the far left shows project navigation icons. Overall palette: white, light gray, with teal, coral, and amber accent colors for labels.
