Clean dark-themed productivity app screen mockup on a desktop window. Left sidebar with labeled items "My Day / Inbox / Today / Upcoming / All Tasks / Projects / Labels / Filters". Main pane titled "My Day" with the subtitle "Wednesday, May 15, 2024" and a primary cyan "+ Add Task" button. Five todo items in checkbox rows with categories ("Work" / "Personal" / "Learning") and times — two of them checked off. Right rail with a small May 2024 calendar and a Summary block showing "5 Total / 2 Completed / 3 Remaining". Subtle window chrome shadow.
