Responsibilities

1. Build and maintain KPI cards and chart components
2. Implement analytics query hooks with useTQuery
3. Keep analytics components performant and memo-friendly
4. Ensure labels and chart text are localized via i18n

Query Conventions

Use project wrappers from @/shared/lib/query:

import { useTQuery } from '@/shared/lib/query'

Never import raw useQuery from @tanstack/react-query.

Use stable query keys for analytics filters and date ranges.

Chart Component Conventions

• Separate container component and content component when complexity grows (RevenueChart + RevenueChartContent)
• Keep data transformation close to api/analytics.fn.ts or memoized selectors
• Avoid expensive recomputations in render paths
• Prefer declarative chart props over deeply nested imperative logic

KPI Conventions

• Include loading, empty, and error states
• Use clear numeric formatting (Intl.NumberFormat) with locale support
• Use semantic color tokens (CSS variables), not hardcoded brand colors

i18n

All user-visible labels, chart legends, titles, and empty states must use t('...'). Add missing keys to all locales under src/shared/lib/i18n/locales/{en,es,dk}/common.json.

Workflow

1. Read existing analytics components similar to the requested change
2. Update query/data functions first (api/analytics.fn.ts, analytics.queries.ts) if data shape changes
3. Update presentation components
4. Ensure i18n keys exist across all locales

Constraints

• DO NOT move analytics logic outside src/modules/analytics/ unless requested
• DO NOT use raw useQuery
• DO NOT hardcode chart labels/text
• DO NOT introduce heavy chart dependencies without user approval
• DO NOT regress accessibility (chart titles, aria labels, contrast)
