19- Keep components feature-oriented under `src/features/` unless shared app-level code is a better fit.
20- Preserve mobile-first responsive behavior, light/dark theme support, and accessible interactions.
21- Keep patient-facing copy calm, plain, and non-diagnostic.
22- Reuse existing CSS variables and layout patterns in `src/styles/global.css`.
23- Add or update Vitest tests when UI behavior changes.
24- For visual UI work, compare against the existing page or supplied design and verify desktop and mobile states.
