Fluid Design

Make interfaces feel like continuous physical systems, not discontinuous state flips.

Composition with other skills

• This skill owns how interaction should feel.
• modern-css-html owns the most native implementation that can still deliver that feel.
• Prefer CSS/HTML when they can express the behaviour.
• Use JavaScript/Motion/SwiftUI when you need interruption, velocity inheritance, gesture continuity, or spring physics CSS cannot express cleanly.
