Emil's Design Engineering Principles

A comprehensive guide for building polished, accessible web interfaces based on Emil Kowalski's design engineering practices.

Choose the scope

• Broad design-engineering pass: read the references that match the surface being built or reviewed. Check structure, interaction, accessibility, visual craft, and performance together.
• Focused polish pass: when a component or small region "feels off," read focused-polish.md. Keep the pass local unless the cause is a shared token, primitive, or layout rule.

For motion work, follow ../animate/references/canonical-policy.md as the canonical policy. It wins when this skill or a companion reference makes a stronger or conflicting claim. Route to animate, css-animations, animation-performance, or animation-accessibility as appropriate.
