description: 'Cloudinary''s marketing surface is media-API technical infrastructure dressed in confident navy-blue. The canvas is pure white `#ffffff` with deep navy `#0d152e` mid-page bands, and the type is Inter at modest mid-weights (500–600 for display) sitting in a structured, dev-tool-credible layout. Brand voltage is `#3448c5` Cloudinary blue — a deep saturated blue that anchors primary CTAs, brand wordmark, and feature accents. Where Stripe is single-color discipline and AWS is enterprise-cool, Cloudinary occupies a media-platform middle ground: technical credibility (code blocks, API references, transformation strings) paired with media warmth (photo galleries, video thumbnails, image-transformation demos). The signature design move is the **transformation chip** — a small horizontal pill showing a Cloudinary URL fragment (`f_auto,q_auto,w_800`) as a code-style accent inline with feature copy. Demo cards carry real before/after image transformations, video player UI, and DAM (digital asset management) interfaces. Section rhythm: white hero → image-transformation demo grid → dark navy code-block band → white feature grid → pricing → footer. The voice is technically confident, dev-friendly, and explicitly capability-focused — Cloudinary writes about MIME types, transformation parameters, and CDN edge nodes alongside the marketing copy.'

---

## 1. Visual Theme & Atmosphere

Cloudinary's marketing surface is media-API technical infrastructure dressed in confident navy-blue. The canvas is pure white `#ffffff` with deep navy `#0d152e` mid-page bands and footer, and the type is Inter at modest mid-weights (500–600 for display) sitting in a structured, dev-tool-credible layout that balances technical reference with marketing warmth.

Brand voltage is `#3448c5` Cloudinary blue — a deep saturated blue that anchors primary CTAs, brand wordmark, and feature accents. Where Stripe is single-color discipline and AWS is enterprise-cool, Cloudinary occupies a media-platform middle ground: technical credibility (code blocks, API references, transformation strings) paired with media warmth (photo galleries, video thumbnails, image-transformation before/after demos).

The signature design move is the **transformation chip** — a small horizontal pill showing a Cloudinary URL fragment (`f_auto,q_auto,w_800`) as a code-style accent inline with feature copy. These chips appear scattered through marketing prose, signaling "this is what the API actually looks like." Combined with multi-line code blocks on dark navy surfaces, the marketing reads as half product page, half developer documentation — which is the brand's distinct positioning.

Demo cards carry real before/after image transformations (a low-quality JPEG transformed to WebP at AVIF), video player UI, and DAM (digital asset management) interfaces. Three accent colors — coral for image transformation moments, amber for quality optimization, mint for video/streaming — appear as pastel surfaces alongside brand-blue, providing visual variety without diluting the blue voltage.

Section rhythm: white hero → image-transformation demo grid → dark navy code-block band → white feature grid → pricing → navy footer. The voice is technically confident, dev-friendly, and explicitly capability-focused — Cloudinary writes about MIME types, transformation parameters, and CDN edge nodes alongside the marketing copy.

**Key Characteristics:**
- Canvas is pure white `#ffffff` with deep navy `#0d152e` for dark bands and footer.
- Brand voltage is `#3448c5` Cloudinary blue — deep saturated, dev-tool credible.
- Display weight is 600 — confident-pragmatic, not aggressive.
- The transformation chip (`f_auto,q_auto,w_800` style) is the signature visual element.
- Code blocks appear as full-width dark navy surfaces with syntax highlighting.
- Three accent colors: coral (transformation), amber (quality), mint (video/streaming).
- Footer is **navy** — matches the hero card-dark, distinctive against white body.
- Section padding is 96px between bands.
- Card radius scale: 18px for feature pastels, 12px for content cards, 8px for primary CTAs and code blocks.

## 2. Color Palette & Roles

### Primary
- **Bg / Canvas** (`#ffffff`): Pure white.
- **Text / Ink** (`#0d152e`): Very dark navy — the same hex as the dark band, signaling intentional unity.
- **Brand / Cloudinary Blue** (`#3448c5`): Primary CTA, brand wordmark, link color, primary feature accent.

### Brand & Dark
- **Brand Hover** (`#2b3da8`): Press state.
- **Brand Active** (`#23328e`): Focused.
- **Brand Soft** (`#e1e5f7`): Blue pastel surface.
- **Brand Deep** (`#1a266b`): Deep navy-blue for layered compositions.
- **Bg Dark** (`#0d152e`): Mid-page band, footer, code block background.
- **Bg Dark Elev** (`#162042`): Elevated dark surface for inline code blocks within dark sections.
- **On-Dark** (`#ffffff`): Pure white on dark surfaces.

### Accent — Three-Color Media Palette
- **Coral** (`#ff5e58` saturated, `#fde0de` soft): Image transformation moments, hero accent dot, danger states.
- **Amber** (`#f5b324` / `#fdedc6` soft): Quality optimization (auto-quality, format-optimization), warning states.
- **Mint** (`#3fc998` / `#d6f3e7` soft): Video / streaming features, success states.

The accent palette is deliberately small (three colors) — Cloudinary's discipline mirrors Stripe's single-blue but extends it with three semantic accents that map to media-domain concepts (image, quality, video).

### Code Syntax Palette
- **Code BG** (`#0d152e`): Same as bg-dark.
- **Code Text** (`#d9e0f5`): Cool-tinted white default text.
- **Code Keyword** (`#7eb6ff`): Light blue for `const`, `function`, `return`.
- **Code String** (`#ffb074`): Warm orange for string literals.
- **Code Comment** (`#8c91a8`): Muted gray for `//` comments.

### Interactive
- **Link** (`#3448c5`): Inline body links — same as brand. Underlines on hover.
- **Link Hover** (`#2b3da8`): Pressed state.
- **Selection** (`rgba(52, 72, 197, 0.18)`): Brand selection.

### Neutral Scale
- **Ink** (`#0d152e`): Display + emphasis.
- **Text Body** (`#2c3354`): Soft navy running-text.
- **Text Muted** (`#5a6080`): Captions, footer links (lift to white-soft inside navy footer).
- **Text Faint** (`#8c91a8`): Placeholder, disabled.

### Surface & Borders
- **Bg** (`#ffffff`): Canvas.
- **Bg Soft** (`#f5f7fb`): Cool-tinted card surface.
- **Bg Strong** (`#e9ecf3`): Pre-footer cool band.
- **Border** (`#dbe0eb`): Default 1px hairline — cool-tinted.
- **Border Strong** (`#a8b0c4`): Stronger card / input border.
- **Border Soft** (`#e9ecf3`): Softest divider.

### Shadow Colors
All shadows use deep-navy-tinted ink `rgba(13, 21, 46, …)` — matches the brand's dark surface. Focus ring is brand at 45%.

### Semantic
- **Info** (`#3448c5`): Same as brand.
- **Success** (`#3fc998`): Mint.
- **Warning** (`#f5b324`): Amber.
- **Danger** (`#ff5e58`): Coral.

## 3. Typography Rules

### Font Family
- **Primary**: `"Inter Display"` for display sizes (≥ 28px); `"Inter"` for body and UI.
- **Mono**: `"JetBrains Mono"` (with `"SF Mono"` and `"Source Code Pro"` fallback) for code blocks, transformation chips, API references.
- **Fallback chain**: `-apple-system, BlinkMacSystemFont, "Segoe UI", Helvetica, sans-serif`.
- **OpenType features**: `ss01`, `cv11` for Inter character; `tnum` for tabular figures in metrics and pricing.

- **JetBrains Mono carries all code.** The choice signals dev-tool credibility.
- **Inline code is weight 500** — heavier than block code (400) so it stands out within body type.
- **Transformation chips use code-micro (12px / 500).** Smaller than inline code, deliberately compressed.
- **Negative tracking scales with size.** -0.022em at 76px to 0 at 16px.
- **Eyebrow tracking is 0.04em.** Subtle uppercase eyebrow voice.
- **Tabular figures inside data tables and metric chips.**

## 4. Component Stylings

### Buttons (5 variants)

**`button-primary`** — Background `#3448c5` Cloudinary blue, white text, type 15px / 600 Inter, padding 12 × 22px, radius 8px. "Sign up free" / "Get started" / "View docs". Hover lightens via 4% white overlay; active darkens. Focus shows 3px brand ring at 45% alpha.

**`button-secondary`** — White, ink text, 1px border `#a8b0c4`, same shape. "Talk to sales" / "View docs".

**`button-tertiary`** — Inline link-style. Transparent, brand-blue text, 10 × 16px padding, 8px radius. Often paired with a chevron icon.

**`button-on-dark`** — White over navy. White background, ink text.

**`button-on-dark-ghost`** — Translucent ghost on navy. Transparent, white text, 1px white-30%-alpha border.

**`button-icon`** — 36 × 36px circular. White, 1px hairline, ink icon.

### Cards

**`card-default`** — Bg-soft cool surface, 12px radius, 32px padding.

**`card-elevated`** — White, 12px radius, 32px padding, 1px border, standard shadow.

**`card-feature-coral` / `amber` / `mint` / `blue`** — Pastel feature cards. Each uses the corresponding `accent-{name}-soft` background (or `brand-soft` for blue), 18px radius, 48px padding. Surface signals feature semantic.

**`hero-card-dark`** — Mid-page navy CTA. `#0d152e`, white text, 18px radius, 64px padding. Often holds an embedded code block.

**`code-block`** — Full-width dark navy surface, 8px radius, 24px padding. JetBrains Mono 14px / 400, syntax-highlighted. Typically 6–12 lines of Node.js, React, or REST API example.

### Transformation Chip (the signature component)

**`transformation-chip`** — Small inline horizontal pill showing a Cloudinary URL fragment. Background `#f5f7fb` bg-soft, brand-blue text, 6px radius, 4 × 8px padding, JetBrains Mono 12px / 500, 1px border `#dbe0eb`. Example contents: `f_auto,q_auto,w_800`, `e_blur:200`, `c_fill,g_auto`. These chips appear scattered through marketing copy as inline code-style accents — the brand's most recognizable visual element.

### Badges & Pills

- **`badge-tag`** — Default category. Bg-soft, muted text, rounded pill, 4 × 10px, 12px font.
- **`badge-new`** — "New" feature pill. Brand-soft surface, brand-active text.

### Inputs / Forms

**`text-input`** — White, 8px radius, 12 × 14px padding, 44px height, 1px `#a8b0c4` border. Inter 16px / 400.

**`text-input-focus`** — Border recolors to brand; 3px brand ring at 20% alpha.

### Navigation

**`top-nav`** — 64px-tall opaque white bar (no backdrop-blur — Cloudinary opts for solid for clean visual weight against image-heavy pages below). Wordmark left in brand blue. Mega-menu center (Products, Solutions, Developers, Resources, Pricing) — opens full-width panel on hover with feature thumbnails. Right cluster carries "Talk to sales" text link, "Login" text link, "Sign up free" `button-primary`.

**`footer`** — **Navy `#0d152e` background**. White text, 96px padding, 5–6 column desktop link grid (Products / Solutions / Developers / Company / Legal). Lower legal row at 12px white-50%-alpha. Includes a small JetBrains Mono code-snippet credit at the very bottom.

### Toasts & Modals

**`toast`** — Navy background, white text, 8px radius, deep shadow.

**Modal** — White, 18px radius, 48px padding, deep shadow, navy-tinted backdrop overlay 70% alpha.

### Decorative

**Before/After transformation slider** — A draggable image comparison slider showing original (left) and Cloudinary-transformed (right) images. The handle is a brand-blue circle with horizontal arrows. Hovering pauses the auto-animation; dragging reveals more or less of either side.

**API request/response block pair** — Side-by-side dark navy code blocks: left shows the API request (POST /upload with parameters), right shows the JSON response. Used in developer-focused feature sections.

## 5. Layout Principles

### Spacing System
Base unit **4px**. Scale: `4 · 8 · 12 · 16 · 20 · 24 · 32 · 40 · 48 · 64 · 80 · 96 · 128`. Section padding **96px** between bands. Card padding 32px (default), 48px (feature pastels), 64px (dark hero), 24px (code blocks).

### Grid & Container
- **Max content width**: 1280px centered.
- **Feature pastel grid**: 2-up at desktop with semantic pairing (image-coral + video-mint, quality-amber + asset-blue). 1-up at mobile.
- **Pricing tier grid**: 4-up at desktop (Free, Plus, Advanced, Enterprise), 1-up at mobile.
- **Code-block + explanation grid**: 2-column at desktop with code on left, explanation on right.

### Whitespace Philosophy
Whitespace is moderate — 96px section padding, 32–64px card padding. Cloudinary balances dev-tool density (code blocks pack information) with marketing breathing room (hero sections use generous white space).

### Section Cadence
White hero → 2-up image-transformation feature pair → dark navy code-block band → white feature grid → 3-up media-format demo → mid-page navy CTA → light pricing → navy footer. The navy bands appear 2× per long page (hero card-dark + footer), bracketing the white body.

## 6. Shapes & Radius Scale

| Tier | Token | Value | Use |
|---|---|---|---|
| Micro | micro | 2px | Cookie / legal CTAs |
| Standard | sm | 6px | Inputs, transformation chips, small chips |
| Comfortable | md | 8px | Default cards, primary CTAs, code blocks, secondary CTAs |
| Relaxed | lg | 12px | Default content cards, elevated cards |
| Featured | xl | 18px | Pastel feature cards, dark hero, modals |
| Pill | pill | 9999px | Status pills, badges |
| Full | full | 9999px / 50% | Avatars, icon buttons |

## 7. Depth & Elevation

| Level | Treatment | Use |
|---|---|---|
| 0 — Flat | No shadow | Canvas, top nav, footer, pastel feature cards |
| 1 — Hairline | 1px `#dbe0eb` border | Default cards, inputs, transformation chips |
| 2 — Ambient | `0 1px 2px rgba(13,21,46,0.05)` | Resting cards |
| 3 — Standard | `0 6px 18px rgba(13,21,46,0.08)` | Card hover, sticky nav at scroll, pricing tiers |
| 4 — Elevated | `0 14px 36px rgba(13,21,46,0.12), 0 2px 6px rgba(13,21,46,0.06)` | Mega-menu, integration cards |
| 5 — Deep | `0 24px 56px rgba(13,21,46,0.18), 0 6px 12px rgba(13,21,46,0.08)` | Modals |

### Shadow Philosophy
Deep navy-tinted shadows match the brand's dark voltage. Pastel cards stay flat. Code blocks have no shadow — they sit flush on the navy band. Modals stack two shadows for compound depth.

## 8. Interaction & Motion

### Easing Curves
- **Standard** `cubic-bezier(0.4, 0, 0.2, 1)`.
- **Emphasized** `cubic-bezier(0.16, 1, 0.3, 1)`.
- **Spring** `cubic-bezier(0.32, 0.72, 0, 1)` — before/after slider physics.

### Duration Buckets
- **Instant (80ms)**: Color hover.
- **Fast (160ms)**: Button hover, focus ring, transformation-chip hover.
- **Standard (240ms)**: Card hover, dropdown, mega-menu, code-block syntax-highlight tooltip.
- **Slow (380ms)**: Pastel reveal, modal entrance, before/after slider auto-animation.
- **Page (480ms)**: Inter-page transition.

### Per-Component Micro-States
- **Button hover (primary)**: 4% white overlay; no transform; 160ms.
- **Card hover (pastel)**: 4px translate-y lift + standard shadow; 240ms emphasized.
- **Transformation chip hover**: Border color shifts `#dbe0eb` → `#3448c5` brand; subtle background tint; 160ms.
- **Code block token hover**: A small tooltip appears explaining the token (e.g., "f_auto: automatic format selection"); 240ms fade-in.
- **Before/after slider**: Auto-cycles 0% → 100% → 0% over 6 seconds with easing; pauses on hover; resumes after pointer-leave.
- **Link hover**: Underline grows 0 → 1px under text; 160ms.
- **Input focus**: Border recolors → brand; 3px ring expands at 20% alpha; 160ms.

### Page Transitions
Default fade. Inter-page route is 480ms emphasized fade-in with 12px translate-y. Section reveals are 380ms fade + 16px offset. Pastel feature cards stagger 80ms increments inside a row.

### Reduced Motion
All transforms removed. Before/after slider falls back to static side-by-side. Code-block tooltips appear instantly without fade.

## 9. Accessibility & A11y

### Contrast Pairs
- **Text on bg**: `#0d152e` on `#ffffff` = **17.6** — AAA.
- **Body on bg**: `#2c3354` on `#ffffff` = **12.2** — AAA.
- **Muted on bg**: `#5a6080` on `#ffffff` = **6.6** — AA.
- **On-brand**: white on `#3448c5` = **7.4** — AAA.
- **On-dark**: white on `#0d152e` = **16.8** — AAA.
- **Link on bg**: `#3448c5` on `#ffffff` = **7.4** — AAA.
- **Code text**: `#d9e0f5` on `#0d152e` = **11.4** — AAA.
- **Code keyword**: `#7eb6ff` on `#0d152e` = **8.0** — AAA.
- **Code string**: `#ffb074` on `#0d152e` = **8.6** — AAA.

### Focus Indicators
3px solid brand at 45% alpha with 2px offset on every focusable element.

### ARIA Patterns
- **Buttons**: Native `<button>`; `aria-label` only for icon-only.
- **Mega-menu**: `role="menu"` with `role="menuitem"`; `aria-expanded` on trigger.
- **Code blocks**: `<pre><code>` with `role="code"`; copy-button has `aria-label="Copy code to clipboard"`.
- **Transformation chips**: `<code>` with optional `<button>` wrapper if interactive.
- **Before/after slider**: `role="slider"` with `aria-valuemin`, `aria-valuemax`, `aria-valuenow` reflecting drag position. Keyboard support: arrow keys move 5%, Page Up/Down move 25%, Home/End move 0/100%.
- **Dialog (modals)**: `role="dialog"` with `aria-modal="true"`, focus trap.
- **Navigation**: `<nav aria-label="Primary">`.

### Keyboard Navigation
Tab order follows visual reading order. Mega-menu opens on Enter/Space, navigates with arrow keys, closes with Escape. Code-block copy button is a separate focusable target.

### Screen Reader Hints
Before/after slider announces "Original image, transformed image — slider at 50%". Code blocks announce "Code block, JavaScript, 8 lines". Transformation chips announce "Cloudinary transformation: f auto comma q auto comma w 800". Decorative API request/response chrome uses `aria-hidden="true"` for non-essential lines.

### Reduced Motion Handling
All transforms removed. Before/after slider becomes static. Pastel reveals fade without offset.

## 10. Responsive Behavior

| Name | Width | Key Changes |
|---|---|---|
| Mobile | < 640px | Single-column body; nav collapses to hamburger; pastel grid 1-up; hero h1 scales to 36px / 600; code blocks become horizontally scrollable; section padding 64px |
| Tablet | 640–1024px | 2-up pastel grid; nav stays horizontal but tightens; mega-menu collapses to single column; hero at 48px |
| Desktop | 1024–1280px | 2-up or 3-up pastel grid; full mega-menu; hero at 60–76px |
| Wide | > 1280px | Same as desktop with more outer breathing room; max content width 1280px |

### Touch Targets
- `button-primary` renders at 44 × 44px minimum.
- `button-icon` is 36 × 36px (under WCAG 44 — used inside dense UI).
- `text-input` height is 44px throughout.

### Collapsing Strategy
- Nav collapses to hamburger at < 640px.
- Mega-menu becomes accordion on tablet.
- Code blocks become horizontally scrollable on mobile rather than wrapping.
- Pricing comparison table converts to horizontally-scrollable swipe at < 1024px.
- Before/after slider preserves its drag interaction at all breakpoints.

### Image Behavior
- Before/after slider images crop to fit container.
- Hero illustrations bleed full-width on mobile.
- Customer logo strip wraps to 2–3 rows at smaller breakpoints.

### Container Queries
Pricing tier cards use `@container (min-width: 360px)` for vertical-to-inline price display.

## 11. Content & Voice

### Tone
**Technically confident, dev-friendly, capability-focused.** Cloudinary writes about MIME types, transformation parameters, and CDN edge nodes alongside marketing copy. Headlines combine dev specificity with marketing claims: "Deliver perfect images and videos at any scale" or "Transform any image with a URL parameter". Body copy explains the technical mechanism — auto-format selection, AI-driven cropping, lazy-load — with concrete code examples.

### Microcopy Patterns
- **CTA verbs**: "Sign up free", "Get started", "View docs", "Talk to sales", "Try it free". Direct, dev-tool-credible.
- **Section eyebrows**: 13px / 600 / 0.04em uppercase — "DEVELOPERS", "MEDIA OPTIMIZATION", "ASSET MANAGEMENT".
- **Feature titles**: One-line capability — "Auto-optimize every image for every device" not "Make images magical".
- **Transformation chip context**: Always inline within a sentence — "Just add `f_auto,q_auto` to your URL and we'll deliver the optimal format."

### Empty States
"No assets yet — upload your first to get started." Single line muted text plus brand-blue CTA link.

### Error Messages
Short, technical, action-oriented. "Upload failed: file size exceeds 10MB limit. Try a smaller file or upgrade your plan." Errors carry coral icon-x and inline guidance with a docs link.

### Success Confirmations
Toast: "Asset uploaded", "Transformation saved", "API key copied". Navy background, white text, 8px radius, deep shadow, auto-dismiss 3s.

### CTA verb conventions
The brand prefers concrete verbs: "Sign up free", "Get started", "View docs", "Try the API", "See pricing". The free-tier nudge is explicit ("25 GB free, no credit card required") and appears under the CTA in legal type.

## 12. Dark Mode & Theming

Cloudinary's in-product dashboard ships a dark variant where canvas inverts to navy `#0d152e`, brand blue lifts slightly to `#5267e0` for AA contrast, and pastel surfaces become tonal navy variants. The marketing surface is **light-only** with the navy footer and dark hero band providing intra-page contrast.

Code blocks on the marketing surface always use the dark navy theme — even on light pages — because syntax highlighting is more legible and dev-tool-credible on dark.

## 13. Lineage & Influences

Cloudinary descends from the **media-API and dev-tool marketing tradition** — Stripe (single-color discipline), Twilio (code-first credibility), Algolia (dev-doc rigor) — and the **enterprise-credibility tradition** — AWS, Akamai, Fastly. The transformation chip is Cloudinary's signature contribution: a code-style inline element that brings the API's actual syntax into marketing copy, blurring the line between marketing page and developer documentation.

The deep navy `#0d152e` references contemporary dev-tool brand colors (Vercel, GitHub, GitLab) but lands distinctively bluer than Vercel's near-black. JetBrains Mono is the dev-tool font of choice across this peer set; Cloudinary's choice signals alignment with the developer audience.

- **Stripe** — Single-color discipline; pricing-page typographic rigor. https://stripe.com
- **Twilio** — Code-first dev-tool credibility; transformation-string prominence.
- **Vercel** — Deep dark surface as primary brand voltage; mono for code.
- **Algolia** — Dev-doc rigor inside marketing copy.
- **JetBrains Mono** — The dev-tool mono font of choice.

## 14. Do's and Don'ts

### Do
- Keep canvas pure white `#ffffff` with deep navy `#0d152e` for dark bands and footer.
- Use brand `#3448c5` Cloudinary blue for the single voltage CTA per viewport.
- Sprinkle transformation chips through marketing copy — they are the brand's signature.
- Use code blocks on dark navy surfaces with full syntax highlighting.
- Anchor every band at 96px vertical padding.
- Use the three accent colors semantically: coral=image transformation, amber=quality, mint=video.
- Use JetBrains Mono for all code — block, inline, and chip.
- Display weight at 600 — confident-pragmatic.
- The navy footer is signature — don't replace with cream/white.
- Pair before/after sliders with brand-blue handle circles.

### Don't
- Don't dilute brand blue. `#3448c5` is the voltage — softening it kills dev-tool credibility.
- Don't use display weight below 500 or above 700.
- Don't use cream / off-white canvas. Pure white is the brand's clarity.
- Don't replace JetBrains Mono with a sans for code. The mono signals dev-tool credibility.
- Don't add atmospheric gradients to hero. White + navy band + transformation chips is the move.
- Don't use the three accents (coral, amber, mint) outside their feature semantic.
- Don't pair coral and amber adjacent — both warm-orange-leaning.
- Don't use light shadow on code blocks. They sit flush on navy with no shadow.
- Don't replace the navy footer with white. The footer is part of the brand voltage.
- Don't use status chips with white text on amber. Amber requires ink text for AA contrast.

### Example Component Prompts

1. "Create a hero band on `#ffffff` canvas with Inter Display 60px / 600 / -0.02em headline ('Deliver perfect images and videos at any scale'), 18px / 400 `#2c3354` subhead at 1.55. Inline transformation chip in the subhead: small pill `f_auto,q_auto,w_800` in JetBrains Mono 12px / 500, brand-blue text on `#f5f7fb` with `#dbe0eb` border. Primary CTA `#3448c5` Cloudinary blue (white, 15px / 600 Inter, 8px radius, 12 × 22px). Secondary CTA white with 1px `#a8b0c4` border."

2. "Build a 2-up media feature pair: coral `#fde0de` left card framing a before/after image transformation slider (low-quality JPEG → AVIF); mint `#d6f3e7` right card framing a video player UI with adaptive bitrate selector. Each card 18px radius, 48px padding. Title in Inter Display 28px / 600 / -0.008em."

3. "Compose a dark navy code block band: full-bleed `#0d152e` background, 96px vertical padding. Embedded code block at 8px radius, 24px padding, JetBrains Mono 14px / 400, syntax-highlighted (keywords in `#7eb6ff`, strings in `#ffb074`). Sample code: 6-line Node.js using `cloudinary.uploader.upload()`. Right-side explanation in 16px / 400 white text at 0.85 opacity."

4. "Design a transformation chip: inline pill, `#f5f7fb` background, `#3448c5` brand-blue text, 6px radius, 4 × 8px padding, JetBrains Mono 12px / 500, 1px `#dbe0eb` border. Sample contents: `f_auto,q_auto,w_800`, `e_blur:200`, `c_fill,g_auto`. Hover: border shifts to brand blue, subtle background tint."

5. "Build a pricing tier card: white surface, 12px radius, 32px padding, 1px border `#e9ecf3`, ambient shadow. Plan name in Inter Display 22px / 600, price in 36px / 600 / -0.014em with `tnum` figures, feature checklist in 16px / 400 with brand-blue check icons. Primary CTA at bottom — Cloudinary blue, 8px radius, 12 × 22px padding."

6. "Design the navy footer: `#0d152e` background, 96px padding. White Cloudinary wordmark left. 5-column link grid (Products / Solutions / Developers / Company / Legal) in Inter 14px / 400 white at 70% alpha. Lower legal row in 12px white-50%-alpha. Tiny JetBrains Mono code-snippet credit at the very bottom: `// Built for developers`."

### Iteration Guide
1. Start with pure white `#ffffff` canvas. Cream is wrong — Cloudinary's clarity needs white.
2. Use brand `#3448c5` for primary CTA and link colors. Both share the same hex — discipline.
3. Sprinkle transformation chips through marketing copy. They are the brand's signature element.
4. Use code blocks on dark navy. Light-mode code blocks read as documentation, not marketing.
5. Match accent surface to feature semantic. Coral=image, amber=quality, mint=video.
6. JetBrains Mono carries all code. Inter is for prose.
7. Display weight is 600. Going to 700 reads as marketing-template.
8. The navy footer is signature. Don't replace with cream/white.
