Implement responsive design for websites and web apps — from standard mobile-first layouts to complex patterns (sticky elements, scroll coordination, data tables, dashboards). Three modes: transform existing sites, build responsive from scratch, or launch a live multi-breakpoint preview. Surfaces design forks where there's no single right answer. Use when building responsive layouts, fixing mobile issues, adding breakpoints, working with sticky/scroll patterns, previewing breakpoints, or when the user mentions responsive, mobile, breakpoints, viewport, adaptive design, or responsive preview.

Motion and interaction design expert based on Emil Kowalski, Jakub Krehel, and Jhey Tompkins' techniques. Two modes — build interactive components with purposeful motion, or audit existing animations to catch AI-slop motion patterns (audit emits a branded HTML report with looping demos). Use when creating, adding, animating, or reviewing UI motion: transitions, hover states, micro-interactions, enter/exit animations, or any motion design work in React, Framer Motion, CSS, or HTML. Provides per-designer perspectives with context-aware weighting.
