Ss Review

UI Design Review

When NOT to use

• For accessibility-only issues → use /ss-a11y
• For Nielsen UX heuristics → use /ss-audit
• For a quick automated check → use /ss-lint
• For non-UI code (data fetching, business rules)

Checklist

1. Design Token Compliance

• [ ] No hardcoded hex colors (use semantic tokens: text-foreground, bg-brand, etc.)
• [ ] No hardcoded px spacing in Tailwind (use p-6 not p-[24px])
• [ ] Shadows use CSS variables (shadow-[var(--shadow-card)])
• [ ] Border radius follows the scale (rounded-md, rounded-lg, rounded-2xl)

2. Component Conventions

• [ ] Uses data-slot attribute
• [ ] Uses cn() for className merging
• [ ] Props typed with React.ComponentProps<>
• [ ] Supports className prop override
• [ ] Named export (not default export for components)
• [ ] No wrapper components that only add a className

3. Accessibility (a11y)

• [ ] Touch targets >= 44x44px for interactive elements
• [ ] focus-visible styles on all interactive elements
• [ ] Proper aria-* attributes where needed
• [ ] Color contrast meets WCAG AA (4.5:1 for text, 3:1 for large text)
• [ ] Animations respect prefers-reduced-motion
• [ ] Images have alt text
• [ ] Form inputs have associated labels

4. Mobile Best Practices

• [ ] No horizontal overflow
• [ ] Touch-friendly spacing between interactive elements
• [ ] Safe area insets handled for notched devices
• [ ] Text sizes >= 12px for readability
• [ ] Scrollable containers have -webkit-overflow-scrolling: touch

5. Performance

• [ ] No unnecessary re-renders (stable references, memoization where needed)
• [ ] Images are lazy-loaded
• [ ] Heavy components are code-split

6. Typography

• [ ] Uses the Pretendard/Inter font stack
• [ ] Font sizes from the 14-step scale (10-48px, see CLAUDE.md)
• [ ] Proper font weights (400, 500, 600, 700)
• [ ] Display text (36-48px): leading-none + tracking-[-0.02em]
• [ ] Heading text (18-24px): leading-snug + tracking-[-0.01em]
• [ ] Body text (14-17px): leading-normal (no custom tracking)
• [ ] Caption uppercase (10-13px): tracking-[0.05em] or tracking-wide
• [ ] No line-height: 1.5 on display/heading text (too loose)

7. Spacing Consistency

• [ ] All spacing values are multiples of 6px (p-1.5, p-3, p-6, etc.)
• [ ] No arbitrary spacing (p-5=20px, gap-3.5=14px are violations)
• [ ] Uses size-* shorthand instead of w-* h-*
• [ ] Uses ms-*/me-* instead of ml-*/mr-* (logical properties)
• [ ] Motion transitions use design tokens (duration-[var(--duration-fast)])

8. Coherence (VISUAL-CRAFT.md §C0 — the "one choice per axis" laws)

> The biggest reason a UI reads as "AI-generated" isn't ugly parts — it's mixed > parts. Check that each axis below uses ONE value system-wide; flag a mix as a real > issue, not a nitpick.

• [ ] One radius personality — sharp (0-4px) OR soft (8-12px) OR pill, applied to every card/button/input/modal. No mixing (e.g. a rounded-none panel with rounded-full buttons).
• [ ] One accent color for interactive emphasis (+ semantic red/green/amber only) — not two+ competing accents.
• [ ] No emoji as UI icons (🚗🧺⭐ as list/nav/status/category markers) — they inject many uncontrolled hues; use one line-icon set in currentColor.
• [ ] Status color = severity, not decoration — a normal/OK/"보통" state is neutral grey (not colored); color marks only the minority of rows that need attention; same value → same color.
• [ ] No decorative hues — favorite stars, category dots, avatars use the accent or grey, not a new color each.
• [ ] One shadow language — same light direction, same scale/tint; not some black + some tinted, some up-lit + some down-lit.
• [ ] One icon family / fill mode / stroke weight across the file.
• [ ] Nested-radius law — an element inside a rounded container uses inner = outer − padding, not the same radius (which bulges).
• [ ] Consistent control heights — buttons, inputs, selects share a height set (e.g. 40px).
• [ ] Errors/states never rely on color alone (icon + text too).
