Replace hardcoded Nord colors with semantic CSS variables across all cospend
pages and shared components (FormSection, ImageUpload, SplitMethodSelector,
UsersList, PaymentModal, BarChart). Remove all dark mode override blocks.
Make BarChart font colors theme-reactive via isDark() + MutationObserver.
Extract reusable SaveFab component and use it on recipe edit and all cospend
edit/add pages. Remove Cancel buttons and back links in favor of browser
navigation. Replace raw checkboxes with Toggle component.
Move fitness measurement add/edit forms to separate routes with SaveFab.
Collapse profile section (sex/height) by default on the measure page.
Document theming rules in CLAUDE.md for future reference.
