budget planning, transaction tracking, and financial dashboards.

- Multi-tenant households with member invites
- Plan: monthly/yearly budget per category with overrides
- Suivi: transaction log with running balance (desktop + mobile quick-entry)
- Dashboard: budget vs tracked breakdown + Chart.js donuts
- Flux: Sankey diagram of income allocation
- WCAG 2.1 AA color tokens, dark mode, accessible tables/forms
- 50 Pest tests
