Buena Labs Design System

Buena Labs Design System

The design language for building where writing and code meet. It provides the colors, typography, materials, and components behind Buena Labs products, and covers two brands: buena, the studio mark, and mrkdwn, the markdown editor.

Foundations

Colors

Near-monochrome with a single blue accent. Full dark and light themes; dark is the default.

Typography

Everything set in Buena Mono — variable weight 100–800, slant 0 to −10°.

Materials

Fills, strokes, and the radius scale. Depth without shadows.

Sound

Five recorded tokens mapped to semantic events: tap, click, open, close, error.

Haptics

The same events as touch — native generators per platform, vibration patterns on the web.

Brands

buena

The studio brand: ring symbol + lowercase wordmark. In prose, always “Buena Labs” — two words, capitalized.

mrkdwn

The markdown editor. Always lowercase, set in Buena Mono — even at the start of a sentence.

Components

114 building blocks, documented with live examples. Each page is also available as Markdown by appending .md.

Parity

The component set tracks three upstreams: Geist (73/73 matched), shadcn/ui (64/64), and etermax (60/60), plus 11 buena originals in none of them. Machine-readable checklist: /design/parity.yaml; per-variant depth audit: /design/parity-elements.yaml.

Geist checklist (73/73)
shadcn checklist (64/64)
etermax checklist (60/60)

Domain-specific (not counted): tool-card, agent-card, skill-card, prompt-card, adapter-card, monitor, privacy, ratings-reviews.

buena originals: editorial-card, feature-card, form, hero-card, media-card, newsletter, stat-card, statusline, tag, terminal, type-tester

Markdown for agents

Every design page is available as Markdown: append .md to the URL (for example /design/colors.md). Machine-readable specifications: /design.md for the brand and site system, and buena-mono.buenalabs.io/design.md for the typeface.

Markdown for agents: /design/introduction.md · spec: /design.md
