+description: An inspired interpretation of Voltagent's design language — a developer-focused AI agent engineering platform whose surface is an unrelenting near-black canvas broken only by a single electric-green brand accent, code-editor mockups inside the hero, and a precise grid of dark feature cards that read like a documentation site dressed as marketing.

+
+## Overview
+
+Voltagent is an AI agent engineering platform built for developers, and the brand wears that audience proudly: a near-black `{colors.canvas}` (`#101010`) page background that runs edge-to-edge with no light-mode counterpart, a single electric-green accent (`{colors.primary}` `#00d992`) reserved for CTAs, status pills, and the brand lightning glyph, and a typography system that pairs sentence-case Inter with SF Mono for inline code and command snippets. The whole page reads like polished documentation that decided to also sell something.
+
+The decorative system is restrained. There is no gradient mesh, no atmospheric backdrop, no illustration suite. Instead, the brand uses small typographic moments — a green code chip (`npx voltagent ...`), a 3-px outlined feature card sitting against the same near-black canvas, a green hairline divider between section bands — to mark its identity. The result is a page that feels engineered: every card has a hairline border, every snippet has a copy-to-clipboard button, every metric is rendered in a numeric monospace.
+
+Type stays calm. Hero display sits at 60 px in regular weight with `-0.65 px` tracking — not a billboard headline, more like a documentation H1. Section headings step down to 36 px / 24 px in similar weights. Body copy is 16 px Inter at line-height 1.65 for the kind of legibility long-form devs expect. Uppercase eyebrows are common — `EVERYTHING YOU NEED` style mono-cap labels above section headlines — and they use Inter at weight 600 with wide positive tracking (`2.52 px` at 14 px).
+
+**Key Characteristics:**
+- A single electric-green accent `{colors.primary}` (`#00d992`) carries every CTA, every status pill, and the brand's lightning logo. No second accent.
+- Dark canvas (`{colors.canvas}` `#101010`) is the only page surface — there is no light-mode rhythm; the entire site reads as one continuous dark surface broken by feature-card boundaries.
+- Hairline-bordered feature cards (`{colors.hairline}` `#3d3a39`, 1 px solid) are the brand's primary chrome — no shadows, no fills, just precise hairline rectangles.
+- A signature dashed-border accent (`1px dashed rgba(79, 93, 117, 0.4)`) appears between sections as a quiet rhythm cue — the brand's only ornamental line.
+- Inter + SF Mono pair carries every typographic role. SF Mono is reserved for code blocks, inline command snippets, and metric counters.
+- Buttons are tight 6 px rounded rectangles (not pills); only inline status tags use the 9999 px full pill.
+
+## Colors
+
+### Brand & Accent
+- **Electric Green** (`{colors.primary}` — `#00d992`): The single brand accent. Every primary CTA, every status pill, every "live" indicator, the brand's lightning glyph itself. Reserved.
+- **Primary Soft** (`{colors.primary-soft}` — `#2fd6a1`): A slightly more muted green used inside button-ghost variants and tooltip / focus indicators.
+- **Primary Deep** (`{colors.primary-deep}` — `#10b981`): The darker green used for inline link colour in body copy.
+
+### Surface
+- **Canvas** (`{colors.canvas}` — `#101010`): The default near-black page background. The only surface mode in the brand's marketing system.
+- **Canvas Soft** (`{colors.canvas-soft}` — `#1a1a1a`): A slightly lighter dark fill used inside code blocks and form inputs to mark them visually distinct against the canvas.
+- **Hairline** (`{colors.hairline}` — `#3d3a39`): 1 px solid borders — feature cards, buttons, dividers between rows. The brand's universal "edge" colour.
+- **Hairline Soft** (`{colors.hairline-soft}` — `#b8b3b0`): A lighter divider tint used in rare on-light secondary contexts.
+
+### Text
+- **Ink** (`{colors.ink}` — `#f2f2f2`): Default text colour on the dark canvas — slightly off-white to reduce contrast strain.
+- **Ink Strong** (`{colors.ink-strong}` — `#ffffff`): Pure-white text for hero headlines and high-emphasis copy.
+- **Body** (`{colors.body}` — `#bdbdbd`): Secondary text — supporting copy, body paragraphs in long-form sections.
+- **Mute** (`{colors.mute}` — `#8b949e`): Lowest-priority on-dark text — captions, fine print, footer secondary lines.
+- **Canvas Text Soft** (`{colors.canvas-text-soft}` — `#f5f6f7`): Used inside code mockups to keep code colour just slightly cooler than the surrounding body text.
+
+### Semantic
+The brand doesn't surface a separate error / warning palette in its public marketing pages — the underlying Docusaurus default semantic palette exists in the design system but is reserved for in-product / docs contexts. Validation cues on the marketing surface use the primary green for success and a muted body grey for missing states.
+
+## Typography
+
+### Font Family
+Two faces carry the system:
+1. **Inter** for every display, body, button, and link role. Weights 400 / 500 / 600 / 700 are the working set. Used with OpenType features `"calt"` and `"rlig"` enabled across the page so the geometric Inter ligatures and contextual alternates render correctly.
+2. **SF Mono** (`SFMono-Regular` with Menlo / Monaco / Consolas / Liberation Mono fallbacks) for inline code, command snippets, terminal mockups, and the brand's numeric counters. Weights 400 / 549 / 550 / 700 are present — the unusual 549 / 550 sub-bold weight gives the mono a "slightly heavier than regular" voice for emphasis.
+
+### Hierarchy
+
+| Token | Size | Weight | Line Height | Letter Spacing | Use |
+|---|---|---|---|---|---|
+| `{typography.display-xl}` | 60px | 400 | 60px | -0.65px | Hero headline ("AI Agent Engineering Platform"). |
+| `{typography.display-lg}` | 36px | 400 | 40px | -0.9px | Section headlines. |
+| `{typography.display-md}` | 24px | 700 | 32px | -0.6px | Sub-section / card-title displays. |
+| `{typography.display-sm}` | 20px | 600 | 28px | 0 | Card titles in dense grids. |
+| `{typography.eyebrow-mono}` | 14px | 600 | 20px | 2.52px | UPPERCASE eyebrow tags ("EVERYTHING YOU NEED"). |
+| `{typography.eyebrow-uppercase}` | 18px | 600 | 28px | 0.45px | Larger uppercase eyebrows above hero subsections. |
+| `{typography.body-lg}` | 18px | 400 | 28px | 0 | Lead paragraphs. |
+| `{typography.body-md}` | 16px | 400 | 26px | 0 | Default body paragraph. |
+| `{typography.body-md-strong}` | 16px | 600 | 24px | 0 | Bolded inline body. |
+| `{typography.body-sm}` | 14px | 400 | 20px | 0 | Secondary body. |
+| `{typography.body-sm-strong}` | 14px | 600 | 23px | 0 | Bold caption / pill-tag labels. |
+| `{typography.caption}` | 12px | 400 | 16px | 0 | Fine print. |
+| `{typography.caption-strong}` | 12px | 500 | 16px | 0 | Bold caption. |
+| `{typography.code}` | 13px | 400 | 18px | 0 | Code blocks, inline command snippets. |
+| `{typography.code-strong}` | 13px | 550 | 16px | 0 | Emphasised inline code (the SF Mono "almost-bold" weight). |
+| `{typography.button-md}` | 16px | 600 | 24px | 0 | Button labels. |
+
+### Principles
+- **Inter regular at 60 px display** is the brand's calming counter to AI marketing's tendency to shout. The light tracking and modest weight read like documentation.
+- **Two-face contrast carries the technical voice.** Inter for narrative; SF Mono for anything that could be typed at a terminal.
+- **Uppercase eyebrow with tracking is the brand's signature label style.** `2.52 px` at 14 px is the documented value.
+
+### Note on Font Substitutes
+- **Sans** — *Inter* is the brand's actual face; substitute is the brand itself when self-hosting is not available.
+- **Mono** — *SF Mono* is Apple-system; *JetBrains Mono* or *Geist Mono* are the best free substitutes.
+
+## Layout
+
+### Spacing System
+- **Base unit**: 4 px; small 5 / 6.4 px values appear inside code-mockup line-height compensation.
+- **Tokens**: `{spacing.xxs}` 2 px · `{spacing.xs}` 4 px · `{spacing.sm}` 8 px · `{spacing.md}` 12 px · `{spacing.lg}` 16 px · `{spacing.xl}` 20 px · `{spacing.2xl}` 24 px · `{spacing.3xl}` 32 px · `{spacing.4xl}` 40 px · `{spacing.5xl}` 48 px · `{spacing.6xl}` 64 px.
+- **Section padding**: hero + content bands use `{spacing.5xl}` 48 px top/bottom.
+- **Card interior padding**: feature cards sit at `{spacing.2xl}` 24 px.
+
+### Grid & Container
+- Marketing container centres at roughly 1200 – 1400 px; content stays edge-to-edge in colour with horizontal gutters of `{spacing.3xl}` on desktop.
+- Feature-card grids: 2-up to 3-up at desktop, 1-up at mobile.
+
+### Responsive Strategy
+
+#### Breakpoints
+
+| Name | Width | Key Changes |
+|---|---|---|
+| Mobile | < 768px | Hero 60→32 px; cards 1-up; nav hamburger. |
+| Tablet | 768–1023px | Cards 2-up; nav stays horizontal. |
+| Desktop | ≥ 1024px | Full 3-up card grids. |
+
+#### Touch Targets
+Buttons render at ~44 px tall (12 px vertical padding + 24 px line-height). Meet WCAG AAA at all breakpoints.
+
+#### Collapsing Strategy
+Nav collapses to hamburger at mobile; the menu overlay keeps the same green CTA pinned at the bottom. Feature-card grids drop to 1-up; hero typography scales fluidly.
+
+#### Image Behavior
+Code-editor mockups render as image-like cards with copy-to-clipboard affordances. No photography in the brand's marketing surface.
+
+## Elevation & Depth
+
+| Level | Treatment | Use |
+|---|---|---|
+| Level 0 — Flat | No shadow, no border. | Full-bleed bands. |
+| Level 1 — Hairline | 1 px solid `{colors.hairline}` border on `{colors.canvas}`. | Default for every feature card and button. |
+| Level 2 — Inset Glow | `0 0 15px rgba(92, 88, 85, 0.2)` subtle outer glow. | Hovering / featured cards. |
+| Level 3 — Modal Stack | `0 20px 60px rgba(0,0,0,0.7), 0 0 0 1px rgba(148,163,184,0.1) inset` heavy drop + inset ring. | Modal / dialog surfaces in-product. |
+
+### Decorative Depth
+- Hairline cards on dark canvas — the brand's only true elevation mode.
+- A 2 px solid `{colors.primary}` green border occasionally marks "featured" or "active" status on a card.
+- A 1 px dashed `rgba(79, 93, 117, 0.4)` divider sits between section bands as a quiet rhythm cue.
+
+## Shapes
+
+### Border Radius Scale
+
+| Token | Value | Use |
+|---|---|---|
+| `{rounded.none}` | 0px | Full-bleed bands. |
+| `{rounded.xs}` | 4px | Smallest inline pills, code inline chips. |
+| `{rounded.sm}` | 6px | Default button and input radius. |
+| `{rounded.md}` | 8px | Card chrome, code-block chrome. |
+| `{rounded.pill}` | 9999px | Inline status tags ("Live", "Beta"). |
+| `{rounded.full}` | 9999px | Circular icon containers. |

+- Background `{colors.canvas}`, text `{colors.ink}` (with the headline at `{colors.ink-strong}` white), padding `{spacing.5xl} {spacing.3xl}`. Headline in `{typography.display-xl}` (60 px / weight 400 / `-0.65 px` tracking). Eyebrow above headline in `{typography.eyebrow-mono}` (uppercase, tracked).
+
+**`content-band`** — the standard content band hosting feature grids.
+- Background `{colors.canvas}`, text `{colors.ink}`, padding `{spacing.5xl} {spacing.3xl}`. Section headline in `{typography.display-lg}`.
+
+**`green-divider-band`** — a thin green-glow band that occasionally separates major sections.
+- Background `{colors.canvas}`, 2 px solid `{colors.primary}` top/bottom border. The brand's only chromatic divider.
+
+### Examples (illustrative)
+
+> Auto-derived kit-mirror demonstration surfaces (`scripts/derive-examples-block.mjs`). Each `ex-*` entry references brand-native primitives so downstream consumers (`/preview-design`, `/generate-kit`) re-skin the same 10 surfaces consistently. `TO_FILL` markers indicate missing primitives — resolve in the LLM judgment pass.
+
+**`ex-pricing-tier`** — Default Pricing tier card. Re-uses feature-card chrome with brand canvas-soft surface.
+- Properties: `backgroundColor`, `textColor`, `borderColor`, `rounded`, `padding`
+
+**`ex-pricing-tier-featured`** — Featured/highlighted tier — polarity-flipped surface (dark fill + light text in light mode, light fill + dark text in dark mode).
+- Properties: `backgroundColor`, `textColor`, `rounded`, `padding`
+
+**`ex-product-selector`** — What's Included summary card — re-purposed for SaaS / B2B verticals (NOT a literal product gallery).
+- Properties: `backgroundColor`, `rounded`, `padding`
+
+**`ex-cart-drawer`** — Subscription summary — re-purposed for SaaS / B2B (line items per add-on, not literal cart).
+- Properties: `backgroundColor`, `rounded`, `padding`, `item-divider`
+
+**`ex-app-shell-row`** — Sidebar nav row inside the App Shell example. Active state uses brand primary as the indicator.
+- Properties: `backgroundColor`, `activeIndicator`, `rounded`, `padding`
+
+**`ex-data-table-cell`** — Default data-table th + td chrome. Header uses mono-caps eyebrow typography; body uses body-sm.
+- Properties: `headerBackground`, `headerTypography`, `bodyTypography`, `cellPadding`, `rowBorder`
+
+**`ex-auth-form-card`** — Sign-in / sign-up card. Re-uses feature-card chrome with text-input primitives inside.
+- Properties: `backgroundColor`, `rounded`, `padding`
+
+**`ex-modal-card`** — Modal dialog surface — same chrome as feature-card with elevated shadow.
+- Properties: `backgroundColor`, `rounded`, `padding`
+
+**`ex-empty-state-card`** — Empty-state illustration frame.
+- Properties: `backgroundColor`, `rounded`, `padding`, `captionTypography`
+
+**`ex-toast`** — Toast notification surface — feature-card shape + medium shadow.
+- Properties: `backgroundColor`, `rounded`, `padding`, `typography`
+
+
+## Do's and Don'ts
+
+### Do
+- Reserve `{colors.primary}` (`#00d992`) for every primary CTA, the lightning logo glyph, and live-status indicators. The green is the brand's centre of gravity.
+- Use the dark `{colors.canvas}` (`#101010`) as the only page surface. There is no light-mode rhythm.
+- Build cards with 1 px `{colors.hairline}` borders, not shadows. Hairlines on dark IS the brand's elevation system.
+- Pair Inter (sentence-case) with SF Mono (inline code, command snippets). Every uppercase moment uses Inter at weight 600 with `2.52 px` tracking — not a separate mono.
+- Use `{rounded.sm}` 6 px for buttons, `{rounded.md}` 8 px for cards, `{rounded.pill}` 9999 px only for inline status tags.
+
+### Don't
+- Don't introduce a light-mode counterpart. The brand is dark-canvas only.
+- Don't use the primary green as a body-text fill. It's CTA-only.
+- Don't drop a soft drop-shadow on cards. The brand uses hairlines + occasional glow, never material shadows.
+- Don't render the hero headline in heavy weight (700+). The brand's display is intentionally calm at weight 400.
+- Don't replace Inter or SF Mono with a different family — both faces are part of the brand's voice and pairing.
