How This Works
When applied to an existing project, follow this sequence:
Scan — Read the codebase. Identify the framework, styling method (Tailwind, vanilla CSS, styled-components, etc.), and current design patterns.
Diagnose — Run through the audit below. List every generic pattern, weak point, and missing state you find.
Fix — Apply targeted upgrades working with the existing stack. Do not rewrite from scratch. Improve what's there.

Typography
Check for these problems and fix them:
Browser default fonts or Inter everywhere. Replace with a font that has character. Good options: Geist, Outfit, Cabinet Grotesk, Satoshi. For editorial/creative projects, pair a serif header with a sans-serif body.
Headlines lack presence. Increase size for display text, tighten letter-spacing, reduce line-height. Headlines should feel heavy and intentional.
Body text too wide. Limit paragraph width to roughly 65 characters. Increase line-height for readability.
Only Regular (400) and Bold (700) weights used. Introduce Medium (500) and SemiBold (600) for more subtle hierarchy.
Numbers in proportional font. Use a monospace font or enable tabular figures (font-variant-numeric: tabular-nums) for data-heavy interfaces.
Missing letter-spacing adjustments. Use negative tracking for large headers, positive tracking for small caps or labels.
Orphaned words. Single words sitting alone on the last line. Fix with text-wrap: balance or text-wrap: pretty.
Color and Surfaces
Pure #000000 background. Replace with off-black, dark charcoal, or tinted dark (#0a0a0a, #121212, or a dark navy).
Oversaturated accent colors. Keep saturation below 80%. Desaturate accents so they blend with neutrals instead of screaming.
More than one accent color. Pick one. Remove the rest. Consistency beats variety.
Mixing warm and cool grays. Stick to one gray family. Tint all grays with a consistent hue (warm or cool, not both).
Purple/blue "AI gradient" aesthetic. This is the most common AI design fingerprint. Replace with neutral bases and a single, considered accent.
Generic box-shadow. Tint shadows to match the background hue. Use colored shadows (e.g., dark blue shadow on a blue background) instead of pure black at low opacity.
Flat design with zero texture. Add subtle noise, grain, or micro-patterns to backgrounds. Pure flat vectors feel sterile.
Perfectly even gradients. Break the uniformity with radial gradients, noise overlays, or mesh gradients instead of standard linear 45-degree fades.
Inconsistent lighting direction. Audit all shadows to ensure they suggest a single, consistent light source.
Random dark sections in a light mode page (or vice versa). A single dark-background section breaking an otherwise light page looks like a copy-paste accident. Either commit to a full dark mode or keep a consistent background tone throughout. If contrast is needed, use a slightly darker shade of the same palette — not a sudden jump to #111 in the middle of a cream page.
Empty, flat sections with no visual depth. Sections that are just text on a plain background feel unfinished. Add high-quality background imagery (blurred, overlaid, or masked), subtle patterns, or ambient gradients. Use reliable placeholder sources like https://picsum.photos/seed/{name}/1920/1080 when real assets are not available. Experiment with background images behind hero sections, feature blocks, or CTAs — even a subtle full-width photo at low opacity adds presence.
