Supanova Redesign Engine

How This Works

When applied to an existing landing page, follow this sequence:

1. Scan — Read the HTML/CSS. Identify the styling method, current design patterns, font stack, color palette, and layout structure.
2. Diagnose — Run through the audit below. Document every generic pattern, weak point, and missing element.
3. Fix — Apply targeted upgrades. Do not rewrite from scratch. Improve what's there while maintaining the existing structure.

Design Audit for Landing Pages

Typography

• Browser default fonts, Inter, or Noto Sans KR. Replace with Pretendard (Korean standard) + premium English display font (Geist, Outfit, Cabinet Grotesk, Satoshi).
• Headlines lack presence. Korean headlines need text-4xl md:text-6xl tracking-tight leading-tight font-bold. Tighten letter-spacing for impact.
• Missing word-break: keep-all on Korean text. Korean words break mid-character without this. Add to all Korean text blocks.
• Body text too wide. Constrain to ~65 characters max width. Increase line-height for Korean readability.
• Only Regular and Bold weights. Introduce Medium (500) and SemiBold (600) for hierarchy depth.
• Numbers in proportional font. Use font-variant-numeric: tabular-nums or monospace for metrics and pricing.
• Orphaned words. Fix with text-wrap: balance on headings.

Color and Surfaces

• Pure #000000 background. Replace with #0a0a0a, #09090b (zinc-950), or tinted dark.
• Oversaturated accent colors. Keep saturation below 80%. Desaturate to blend elegantly with neutrals.
• Multiple accent colors competing. Pick ONE. Remove the rest.
• Purple/blue "AI gradient" aesthetic. The most common AI design fingerprint. Replace with neutral bases + single considered accent.
• Generic box-shadow. Tint shadows to background hue. Dark blue shadow on blue background, not rgba(0,0,0,0.3).
• Flat design with zero texture. Add subtle noise overlay, mesh gradient background, or micro-patterns.
• Random dark section in a light page. Maintain consistent background tone. Use shade variations, not dramatic jumps.
• Empty flat sections. Add background imagery (blurred, masked), ambient gradients, or pattern overlays.

Layout (Landing Page Specific)

• Everything centered and symmetrical. Break symmetry with offset margins, mixed aspect ratios, split-screen layouts.
• Three equal card columns for features. The most generic AI layout. Replace with Bento grid, zig-zag alternating, or horizontal scroll.
• Every section uses the same layout. Adjacent sections MUST use different patterns. Hero (split) → Features (bento) → Testimonials (masonry) → CTA (full-bleed).
• Using height: 100vh. Replace with min-height: 100dvh for iOS Safari compatibility.
• No max-width container. Add max-w-7xl mx-auto px-4 sm:px-6 lg:px-8.
• Missing whitespace. Double the section padding. py-20 md:py-32 minimum for landing page sections.
• Cards of forced equal height. Allow variable heights or use masonry.
• No overlap or depth. Use negative margins, z-index layering, or overlapping elements for visual depth.
• CTA buttons not prominent enough. CTAs need px-8 py-4 text-lg minimum. Must be the most visually dominant element.

Interactivity and States

• No hover states on buttons. Add hover:scale-[1.02], background shift, or translate effect with smooth transition.
• No active/pressed feedback. Add active:scale-[0.98] for tactile click feel.
• Instant transitions. Add transition-all duration-300 ease-out to all interactive elements.
• No scroll animations. Add fade-up reveals using CSS @keyframes + IntersectionObserver.
• No loading states for interactive elements. Add skeleton shimmer or loading indicators.
• Static logo strips. Convert to auto-scrolling CSS marquee for trust logos.
• Dead href="#" links. Remove or visually disable them.
• No smooth scroll. Add scroll-behavior: smooth to html.

Korean Content Quality

• Translated-sounding Korean. Rewrite in native, natural Korean. "지금 시작하세요" not "시작을 하세요 지금".
• Mixed honorific levels. Stick to one: 합니다/하세요 consistently.
• AI copywriting cliches. Remove: "혁신적인", "원활한", "차세대", "게임 체인저", "한 차원 높은". Use concrete language.
• Generic placeholder names. Replace "김철수", "이영희" with realistic modern names: "하윤서", "박도현", "이서진".
• Fake round metrics. Replace 50,000+ with 47,200+. Replace 5.0/5.0 with 4.87/5.0.
• English placeholder text. All visible content must be in Korean.
• Lorem Ipsum. Replace with real Korean draft copy immediately.

Component Patterns (Landing Page)

• Generic hero with centered text over solid color. Split screen, full-bleed media, or asymmetric statement layout.
• 3-card feature row. Replace with Bento grid, zig-zag alternating, or horizontal scroll strip.
• Carousel testimonials with dots. Replace with masonry wall, embedded social-style cards, or single rotating quote with large portrait.
• Pricing table with 3 identical towers. Highlight recommended tier with color, scale, and emphasis.
• Footer link farm with 4+ columns. Simplify to essential nav, legal links, social icons.
• Accordion FAQ. Replace with side-by-side list, searchable help, or expandable inline sections.
• CTA that blends into surrounding content. CTAs need dramatic visual contrast — different background, larger padding, floating treatment.

Icons and Images

• Lucide or Feather icons. Replace with Iconify Solar icon set for consistency.
• Broken Unsplash URLs. Replace with picsum.photos/seed/{name}/{w}/{h} for landscapes, i.pravatar.cc/150?u={name} for avatars.
• Missing favicon. Add a branded favicon.
• Inconsistent icon stroke widths. Standardize all icons to one weight (Solar set handles this automatically).
• Generic stock "team" photos. Use consistent illustration style or high-quality contextual photography.

Code Quality

• Div soup. Use semantic HTML: <nav>, <main>, <section>, <article>, <footer>.
• Missing meta tags. Add <title>, <meta name="description">, <meta property="og:image">, <meta name="viewport">.
• No lang="ko" on <html>. Add it for accessibility and SEO.
• Images without loading="lazy". Add lazy loading to all below-fold images.
• No alt text on images. Add descriptive Korean alt text.
• Arbitrary z-index values. Establish: nav (40), overlay (50), decorative (60).

Upgrade Techniques

Typography Upgrades

• Animated text reveals. Characters or words fade/slide in sequentially on scroll.
• Gradient text accent. ONE key headline with subtle gradient fill (max one per page).
• Variable weight on hover. Text weight shifts subtly when interactive elements are hovered.

Layout Upgrades

• Broken grid / asymmetry. Elements that deliberately offset from the column structure.
• Parallax depth. Background images scroll at different speeds from content.
• Sticky scroll stacking. Sections stick and layer over each other during scroll.
• Full-bleed section transitions. Sections bleed into each other with gradient or diagonal transitions.

Motion Upgrades

• Staggered entry cascades. Elements enter with animation-delay: calc(var(--index) * 80ms).
• Spring-based hover. transition: all 0.4s cubic-bezier(0.16, 1, 0.3, 1) on interactive elements.
• Scroll-driven progress. Progress bars or SVG line drawings tied to scroll position.
• Marquee logos. Client logos in an infinite CSS marquee animation.

Surface Upgrades

• True glassmorphism. backdrop-blur-xl + border border-white/10 + inner shadow.
• Mesh gradient backgrounds. Multiple radial-gradient layers for organic ambient feel.
• Noise texture overlay. Fixed pointer-events-none element with subtle grain.
• Tinted shadows. Shadows that carry the background hue instead of generic black.

Fix Priority

Apply in this order for maximum visual impact, minimum risk:

1. Font swap to Pretendard — instant premium feel for Korean content
2. Color palette cleanup — remove AI purple, desaturate accents
3. Korean content rewrite — natural copy, real names, organic numbers
4. Hover and active states — make the interface feel alive
5. Layout diversification — break the same-section repetition
6. Section animation — staggered reveals, scroll triggers
7. Polish spacing and typography — the premium final touch

Rules

• Do not break existing page structure. Improve incrementally.
• Output must remain a single standalone HTML file.
• Before adding any CDN dependency, verify the URL is correct and from a major provider.
• Keep changes focused and reviewable. Targeted improvements over total rewrites.
• All content modifications must maintain natural Korean language quality.
