Minimalist Notion × OpenAI UI

Build crisp, low-noise product UI with strong hierarchy and operator-grade usability.

Core Principles

1. Prioritize clarity over decoration.
2. Keep layout breathable but dense enough for serious work.
3. Use typography, spacing, and contrast as the primary hierarchy tools.
4. Avoid visual noise (heavy shadows, flashy gradients, random color accents).
5. Every element must justify its presence.

Workflow

1. Define screen intent in one sentence.
2. Choose one primary user action.
3. Build skeleton with spacing + typography first (no color dependency).
4. Add semantic color only for state/meaning.
5. Run the checklist in references/qa-checklist.md.
