description: "A developer-tools brand for AI-agent tool integration whose marketing surfaces lean into a dark, technical aesthetic with a single deep-electric-blue voltage (`#0007cd`). The page floor is near-black (`#0f0f0f`); cards float above on subtle gray-tinted surfaces. abcDiatype carries display and body in a single sans family with weights 400-600. The brand's strongest visual signature is a four-pane terminal-style mockup (a 2×2 grid of dark code/output panels) with a central blue spotlight glow — used as the homepage hero anchor."

## Overview

Composio's marketing site reads like a serious developer-infrastructure brand — closer to Vercel or Stripe Docs in atmosphere than to a typical AI-tools startup. The base canvas is a near-black `{colors.canvas}` (#0f0f0f) holding white type and a single voltage of **deep electric blue** (`{colors.primary}` — #0007cd) carrying every primary CTA, brand wordmark, and atmospheric spotlight glow that backs the homepage hero.

Type runs **abcDiatype** as the single sans family across display, body, navigation, and captions. Display sits at weight 500 — confident but not bombastic. Code blocks and terminal mockups switch to JetBrains Mono.

The page rhythm is monolithic: dark canvas top to bottom with subtle elevation steps via card surfaces. The brand's strongest visual signature is a **four-pane terminal-style mockup** — a 2×2 grid of dark code/output panels with a central blue spotlight glow behind them.

**Key Characteristics:**
- Single accent: `{colors.primary}` (#0007cd) for primary CTAs, wordmark, spotlight glows.
- Single sans family: abcDiatype carries everything except code (JetBrains Mono).
- Dark monolithic canvas: `{colors.canvas}` runs top to bottom; depth from `{colors.surface-card}` and `{colors.surface-card-elevated}` brightness steps.
- Terminal-mockup hero: 2×2 grid of code/output panes is the brand signature.
- Compact pill geometry: CTAs sit at `{rounded.md}` (8px), not full pills — developer-tool dialect.
- Spotlight-glow atmospheric backdrop: a radial blue glow centered behind hero content.
- 96px section rhythm.

## Colors

## Typography

### Font Family
The system runs **abcDiatype** (Lineto) across every text role. Code blocks switch to **JetBrains Mono**. Fallback: `ui-sans-serif, system-ui, sans-serif`.

### Hierarchy

| Token | Size | Weight | Line Height | Letter Spacing | Use |
|---|---|---|---|---|---|
| `{typography.display-mega}` | 72px | 500 | 1.05 | -2.16px | Homepage hero h1 |
| `{typography.display-xl}` | 56px | 500 | 1.05 | -1.68px | Subsidiary heroes |
| `{typography.display-lg}` | 44px | 500 | 1.1 | -1.32px | Section heads |
| `{typography.display-md}` | 32px | 500 | 1.15 | -0.96px | Sub-section heads |
| `{typography.display-sm}` | 24px | 500 | 1.25 | -0.5px | Card group titles |
| `{typography.title-md}` | 18px | 600 | 1.4 | 0 | Component titles |
| `{typography.title-sm}` | 16px | 600 | 1.4 | 0 | Toolkit card titles |
| `{typography.body-md}` | 16px | 400 | 1.5 | 0 | Default body |
| `{typography.body-sm}` | 14px | 400 | 1.5 | 0 | Footer body |
| `{typography.caption}` | 13px | 400 | 1.4 | 0 | Photo captions |
| `{typography.caption-uppercase}` | 11px | 600 | 1.4 | 0.88px | Section labels, badge pills |
| `{typography.code}` | 13px | 400 | 1.5 | 0 | Code blocks — JetBrains Mono |
| `{typography.button}` | 14px | 500 | 1.0 | 0 | CTA pill labels |
| `{typography.nav-link}` | 14px | 500 | 1.4 | 0 | Top-nav menu |

### Principles
- **Display weight stays at 500.** Confident but not display-bold.
- **abcDiatype across every role.** No display/body family split.
- **JetBrains Mono on every code surface.**

### Note on Font Substitutes
abcDiatype is a Lineto licensed typeface. Open-source substitute: **Inter** at weight 500 with letter-spacing -1.5%.

## Layout

### Spacing System
- **Base unit:** 4px.
- **Tokens:** `{spacing.xxs}` 4px · `{spacing.xs}` 8px · `{spacing.sm}` 12px · `{spacing.base}` 16px · `{spacing.md}` 20px · `{spacing.lg}` 24px · `{spacing.xl}` 32px · `{spacing.xxl}` 48px · `{spacing.section}` 96px.
- **Section padding:** `{spacing.section}` (96px) for major bands.

### Grid & Container
- Max content width: ~1200px.
- Editorial body: 12-column grid.
- Terminal mockup grid: 2×2 equal-size panes.
- Toolkit grid: 4-up at desktop, 2-up tablet, 1-up mobile.
- Footer: 5-column at desktop.

### Whitespace Philosophy
The dark canvas creates its own depth — whitespace can stay tight without feeling crowded. 96px between bands; 24px between cards inside a band.

## Elevation & Depth

The system uses **brightness-step elevation**: surfaces step up in brightness instead of casting drop shadows. Combined with subtle radial blue glows, this creates a focused dark-mode atmosphere.

| Level | Treatment | Use |
|---|---|---|
| Flat (canvas) | `{colors.canvas}` (#0f0f0f) | Body bands, footer |
| Recessed | `{colors.canvas-deep}` (#000000) | Terminal mockup grid background, code blocks |
| Card | `{colors.surface-card}` (#181818) | Default content cards |
| Card elevated | `{colors.surface-card-elevated}` (#222222) | Terminal panes, secondary buttons |
| Atmospheric glow | Radial gradient using `{colors.primary-glow}` | Hero spotlight backdrop |

### Decorative Depth
- **Spotlight glow backdrops** — radial blue gradient centered behind hero content.
- **Terminal-pane brightness ladder** — 2×2 mockup uses canvas-deep outer + surface-card-elevated panes.

## Shapes

### Border Radius Scale

| Token | Value | Use |
|---|---|---|
| `{rounded.none}` | 0px | Reserved |
| `{rounded.xs}` | 4px | Inline tags |
| `{rounded.sm}` | 6px | Compact rows |
| `{rounded.md}` | 8px | CTA buttons, form inputs |
| `{rounded.lg}` | 12px | Toolkit cards, code blocks, terminal panes |
| `{rounded.xl}` | 16px | Feature cards, terminal mockup grids |
| `{rounded.pill}` | 9999px | Section-label badges |
| `{rounded.full}` | 9999px | Avatar plates (rare) |

Compact developer-ergonomic radii — 8px CTAs, 12-16px cards. Signals "developer tool" rather than "consumer brand."

## Do's and Don'ts

### Do
- Reserve `{colors.primary}` for primary CTAs, wordmark, and spotlight glows.
- Use `{rounded.md}` (8px) for every CTA — not full pills.
- Use brightness-step ladder for elevation; avoid drop shadows.
- Pair every hero with a centered radial blue spotlight glow.
- Render code, CLI commands in JetBrains Mono via `{typography.code}`.
- Use the 2×2 terminal-mockup grid as the homepage hero anchor.

### Don't
- Don't introduce a secondary brand color. Cyan and violet are illustrative-only.
- Don't use full pills on CTAs.
- Don't drop display weight to 400.
- Don't add drop shadow tiers.
- Don't use canvas-deep (#000000) outside terminal/code surfaces.
- Don't extract a CTA color from a third-party widget (cookie consent, OneTrust). The brand's CTA color is what appears on actual page CTAs.

## Responsive Behavior

### Breakpoints

| Name | Width | Key Changes |
|---|---|---|
| Mobile | < 640px | Hero h1 72→36px; terminal mockup grid collapses to single pane; toolkit grid 1-up; nav hamburger. |
| Tablet | 640–1024px | Hero h1 56px; terminal mockup grid stays 2×2; toolkit grid 2-up. |
| Desktop | 1024–1280px | Full hero h1 72px; full 2×2 terminal mockup; toolkit grid 4-up. |
| Wide | > 1280px | Content caps at 1200px. |

### Touch Targets
- Primary CTA at 40px height — at WCAG AA, padded for AAA.
- Search input at 40px.

### Collapsing Strategy
- Top nav switches to hamburger below 768px.
- Terminal mockup 2×2 grid collapses to a single pane on mobile.
- Toolkit grid: 4-up → 2-up → 1-up.
- Hero spotlight glow stays at every breakpoint.

## Iteration Guide

1. Focus on a single component at a time.
2. CTAs default to `{rounded.md}` (8px). Cards use `{rounded.lg}` or `{rounded.xl}`.
3. Variants live as separate entries inside `components:`.
4. Use `{token.refs}` everywhere — never inline hex.
5. Hover state never documented.
6. abcDiatype 500 for display, 400/600 for body. JetBrains Mono on every code surface.
7. Composio Blue stays scarce.

## Known Gaps

- abcDiatype is licensed; Inter is the substitute.
- Animation timings out of scope.
- In-product surfaces (toolkit dashboards, agent playground) are behind login walls.
- Form validation states beyond focus not visible on captured surfaces.
