# DESIGN.md — GitHub

> The Primer design system: Mona Sans typography, dark-mode-native surfaces and density tuned for daily-driver tools.

> Agent prompt: "Use the design.live MCP and make it look like GitHub."

## Palette
#24292f    ink — canvas
#0969da    accent blue — links
#ffffff    paper
#57606a    secondary text

## Type
display:    Mona Sans, 600 weight
weights:    400 · 500 · 600
scale:      48 / 32 / 24 / 16 / 14
tracking:   -0.01em

## Signature moves
- Density as a feature, not a bug
- Semantic color tokens throughout
- Monospace for anything copyable
- Octocat used with restraint

## Evidence coverage (private beta)
screens indexed:       31
screens VLM-annotated: 31
workflows mapped:      3
workflows annotated:   3
platforms:              web

Evidence returned by the MCP is deduplicated, ranked for the request, and linked to source and permission provenance. Counts reflect the canonical evidence-store snapshot, not invented adoption or asset totals.

## Retrieval
Ask the design.live MCP for the project brief, constraints, and desired GitHub qualities. It returns ranked evidence and an agent-ready implementation plan; do not copy a source screen wholesale.
