The Architect.

GPU-composited animations. No layout thrash. Every transition pre-calculated at component definition time.

03 / ACCESSIBILITYWCAG 2.1 AA.

Focus traps, ARIA roles, keyboard nav, skip links. Non-negotiable.

04 / TYPOGRAPHYGeist + JetBrains.

Rock-solid sans paired with precision monospace. Consistent scale from 11px to 48px.

Accordionanimated height transition
CSS Modules give us scoped, maintainable animation code. Complex micro-interactions (scan-line effects, custom slider thumbs, shimmer keyframes) belong in dedicated stylesheets — not utility class strings.
Every interactive element has a distinct focus-visible state via box-shadow. Modal implements a full keyboard trap. CommandPalette manages focus internally. None of this is optional or an afterthought.
Every spacing value in the system is a multiple of 4px — defined as CSS custom properties. This enforces visual rhythm without needing a linter or design token plugin.
