Delivered two key improvements in 2025-10 for navikt/pensjon-verdande that enhance stability, UX, and visual consistency. Implemented a styled ErrorBoundary with route-specific and general error handling, including a dedicated 403 (IkkeTilgang) pathway, and completed a theme migration to the darkside CSS for consistent styling. Result: improved user-facing error messaging, reduced confusion on access errors, a more cohesive UI with dark mode, and a maintainable foundation for future error handling and theming.
