WCAG Accessibility (EN 301 549 / European Standard)
The Standard
The European Accessibility Act (EAA) requires digital products and services in the EU to meet EN 301 549, which references WCAG 2.2 Level AA as the technical baseline. This is not optional — it is a legal requirement for products operating in the EU market.
Default: always build to WCAG 2.2 AA. Deviating requires explicit, documented justification. Do not skip accessibility requirements because of timeline pressure or design preference.
WCAG 2.2 AA organises requirements under four principles: Perceivable, Operable, Understandable, Robust.
Perceivable
Users must be able to perceive all content and UI components.

nielsen-usability-heuristics
UI design and review should apply Nielsen's 10 Usability Heuristics — the foundational principles for evaluating and improving usability. Use when auditing an interface, designing interaction flows, writing error messages, or reviewing any UI for usability issues.
53color-mode-and-theme
Choose light, dark, or combined color mode deliberately based on brand tone and user context. Offer a theme selector only when user control genuinely matters — enterprise tools, data-heavy UIs, or extended-use applications. Use when defining the base color palette, designing a design system, or deciding whether to build dark mode support.
53user-flows-and-guided-paths
Related features and tasks — such as purchase flows, onboarding, or multi-step configuration — should be designed as natural, guided paths that feel coherent and fit the product hierarchy. Use wizards for complex sequential tasks. Use when designing flows, onboarding, checkout, setup sequences, or any multi-step user journey.
52form-design
Forms have three layers of guidance: helper text below the input explains what to enter, placeholder shows the expected format, and validation confirms correctness. Real-time validation for complex inputs. Submit enables only when the form is valid. Use when designing or reviewing any form, input field, or data entry UI.
52button-states
Every interactive element needs a complete set of visual states — rest, hover, active/pressed, focus, disabled, and loading. States should be derived algorithmically from the base colour, not chosen arbitrarily. Use when designing buttons, links, inputs, or any clickable component.
51semantic-html-and-seo
Semantic HTML5, SEO fundamentals, alt texts, progressive enhancement, SPA considerations, device capability detection, and user context awareness. Good HTML is the foundation of accessibility, SEO, and resilient UI. Use when building any web UI, reviewing markup quality, or optimising for search and accessibility.
