ux-principles

Plans, designs and reviews user interfaces and flows with Playwright as the verification loop - task and flow design, screen specs with all states, accessibility plans, acceptance criteria as Playwright checks, plus Nielsen heuristics, laws of UX, WCAG 2.2 AA, deceptive-pattern checks and a script capturing screenshots, axe-core violations and focus order. Use when planning or designing a page, form, component or user flow, defining its UX acceptance criteria, or auditing a running UI; load it before designing so every decision cites a heuristic, law or WCAG criterion.
