◇ Could this help me?
Yes. The two steps carrying most of the value are the standing design instruction and the screenshot-driven revision loop, because together they give the assistant persistent direction and precise visual feedback, which is exactly what it lacks by default. Adopt the first step with judgment: reference a layout's structure and proportions rather than reproducing another company's identity, colors, and copy. This is a general practice.
Improve the visual design of this site in a specific order and stop for my review after each step. First, add a design section to the project instructions defining the visual standard, the type scale, the palette, and the spacing rhythm, so the direction persists across every future prompt. Second, move hand-rolled elements onto an established component library. Third, add considered backgrounds, hover states, and motion, keeping animation to transform and opacity for performance. Fourth, pick a heading and body font pairing and justify the choice. Then I will send screenshots and point at what to fix.
