Stage 1 was really just about getting the frame right before touching any real functionality. I built the visual shell first — a blueprint/schematic-style theme, subtle grid in the background, custom colors, three fonts working together (a technical display font, a normal body font, and a monospace one for the data-y bits) — trying to make it feel like an engineering tool instead of just another to-do app.Then I got the navigation actually working: figuring out the correct Monday-start week from any date, letting you go back and forward a week, jump to today. Added a day strip up top you can tap to jump around, and a swipeable carousel below it — one page per day, snapping into place so it feels natural on iPad instead of clunky.I left the actual tasks out on purpose. Each day’s just a placeholder for now, and the Routines tab is greyed out. Wanted to make sure the swiping, tapping, and week switching all felt smooth before I piled state and storage on top of it.
