Nice, let’s line up the pixels like a row of soldiers and the code like a clean stack of bricks. First, lock every dimension in a design system—use a single source of truth for spacing, font sizes, and animation timings. That way every component pulls from the same constants and you avoid half‑pixel misalignments. Next, think component‑wise: each step of the wizard should be its own reusable unit with an explicit interface—props or context, not hidden globals. Keep the transition logic in a thin wrapper that just drives the animation, not the content. That keeps the render tree lean and the state predictable. If you’re using a framework like React, move the animation state to a context or a dedicated reducer so the UI stays declarative. Use CSS keyframes or a small animation library that respects those design constants; don’t reinvent easing curves on the fly. Finally, write a tiny integration test that snaps a screenshot of each step and compares pixel by pixel to a reference image. That gives you a safety net without manual QA, and if a design change breaks the pixel grid, the test will flag it immediately. Keep the code clean, keep the pixels aligned, and you’ll have a wizard that feels both flawless and maintainable.
