Principles
- Don't assume — If it's not specified, the developer will guess. Specify everything.
- Use tokens, not values — Reference
spacing-mdnot16px. - Show all states — Default, hover, active, disabled, loading, error, empty.
- Describe the why — "This collapses on mobile because users primarily use one-handed" helps developers make good judgment calls.
