# Mobile App DESIGN.md
## Product feel
A launch-ready mobile app style file for AI coding agents, with typography, spacing, component rules, and layout taste.
Build for a Vercel-style, Monochrome UI, Devtool visual taste. Keep density practical, typography strong, and layouts easy for AI agents to repeat.
## Color direction
- Primary text: #0f172a
- Accent / interactive: #8b5cf6
- Surface: #eef2ff
- Border / separators: #c4b5fd
## Typography
- Use a modern sans for body copy and a sharper display face for hero/page titles.
- Titles should feel deliberate, not shouty. Avoid oversized marketing fluff.
- Meta text should stay compact and quiet.
## Layout rules
- Prefer light UI by default.
- Use compact spacing and card grids that still feel breathable.
- Keep navigation practical: search first, then filters, then actions.
- This entry belongs to the "all" lane.
## Components
- Buttons: slightly rounded, clear hierarchy, only one primary CTA per section.
- Cards: soft border, useful metadata, preview-first composition.
- Empty states: helpful, never dead.
- Code panels: mono, dense, copy-friendly.
## Agent rules
- Do not generate generic Tailwind marketing blocks.
- Respect the palette and keep component states consistent.
- Optimize for these tools: Cursor, Claude Code, Codex, Google Stitch, Lovable, Bolt, v0, Figma Make.
## Accessibility
- Preserve contrast for text and controls.
- Use visible focus states.
- Avoid relying on color alone for meaning.
