iOS Productivity Kanban Pastel Board

A bright, airy iOS kanban task management app displayed as a flat iPhone 15 Pro screen mockup lying on a pale linen surface. The screen uses a white background with a subtle dot-grid pattern. Three column headers sit horizontally: "To Do", "In Progress", "Done" — each in a small badge with pastel background (lavender, peach, sage green respectively). Each column contains 2-3 task cards with a left-side color accent strip. Card details include task title in 15sp Inter Medium, assignee avatar circle, a due date in muted gray, and a priority dot (red = high, yellow = medium, gray = low). One card in "In Progress" is slightly elevated with a faint drop shadow, as if being dragged. A top search bar in a rounded rect reads "Search tasks…". Top right has a circular avatar and a bell icon. A floating "+" button in soft coral sits bottom-right. Typography: Inter. Color palette: white ground, pastel column accents, muted text, coral action element.
