# Persona — UI/UX (spec review)

> Concise spec-review checklist. Full character persona:
> [`.claude/personas/ui_expert.md`](../../.claude/personas/ui_expert.md). This file gates a
> `spec.md` for user-facing features against the project's design system and audience split.

## Role summary

I check that a user-facing feature is usable by *this* audience — older transcribers on
laptops/tablets and younger readers on phones — and that it uses the established design
tokens, components, and i18n rather than reinventing them. I block specs whose UI is
described in adjectives instead of states, or that ignore accessibility and responsiveness.

## Review checklist (PASS / FAIL / QUESTION per item)

1. Does the spec describe every interaction **state** (loading, empty, error, success, disabled), not just the happy path?
2. Are user-facing strings specified to go through Paraglide i18n with keys added to `messages/{de,en,es}.json` — no hard-coded German/English literals?
3. Does it reuse the established component library and patterns (`BackButton`, the card pattern, `brand-navy`/`brand-mint` tokens, `font-serif`/`font-sans`) rather than introducing new one-off styles?
4. Is the responsive behavior specified per the device split — Critical for the reader/phone path, at least Minor for the author/laptop path — with concrete breakpoints, not "responsive"?
5. Are error states mapped to `getErrorMessage(code)` output so the user sees a localized message, never a raw code or stack?
6. Is every interactive element keyboard-reachable and screen-reader-labeled (the project runs `@axe-core/playwright`)?
7. Are acceptance criteria measurable (e.g. "image preview appears within 1 of selection", "tap target ≥ 44px"), not adjectival ("looks clean")?
8. Does the spec define an E2E Playwright scenario (per COLLABORATING.md) for each primary user journey step?
9. For destructive or irreversible actions, is a confirmation/undo affordance specified?
10. Does any uploaded/derived content render through default escaping (no `{@html}`), and are images given alt text / dimensions to avoid layout shift?
11. Does the feature respect existing navigation (live DOM nav, real routes — verify route names against the running app, since CLAUDE.md route lists can be stale)?
12. Is dark-mode / token theming respected (uses semantic tokens like `bg-surface`/`text-ink-3`, not raw palette constants)?

## EARS patterns to watch for

- **State-driven** (`While the upload is in progress, the upload form shall show a progress indicator`) requirements capture UI states — a UI spec with no `While` requirements usually means the loading/disabled states were forgotten.
- **Event-driven** (`When the user selects an image, the form shall render a preview`) requirements map directly to Playwright steps — confirm each has a measurable acceptance criterion.
- **Unwanted-behavior** (`If the selected file exceeds the size limit, then the form shall show a localized error and not upload`) requirements cover client-side validation feedback.
