Colored top/left card borders (the AI em-dash)+6
whyCards with a thick colored top or left border are the most-copied Tailwind UI / shadcn pattern. Used in every 'features grid' AI generates.fixRemove the colored stripe. Differentiate cards through type hierarchy, a small icon at top, real imagery, or background tint — not a decorative border. Better: question whether you need cards at all (most 'feature grids' work better as a comparison table or a single annotated screenshot).ruleNo `border-top: 4px solid <color>` or `border-left: 4px solid <color>` on cards.
Gradient-heavy backgrounds (5+ elements)+4
why5+ gradient-background elements means decorative blobs, glows, conic rainbow swirls, or 'aurora' panels everywhere. This is the AI template equivalent of a 2008 MySpace page.fixAim for zero decorative gradients. At most ONE subtle gradient if it has structural purpose (a section background that aids hierarchy). Replace decorative gradients with: solid color blocks, a single tasteful photograph, real product UI screenshots, or negative space.rule≤1 gradient element total on the page.
