 - [Phase 03-collapsible-dashboard-sections]: Direction-aware diff: spending types (bill, variable_expense, debt) over when actual > budgeted; income/saving/investment over when actual < budgeted
 - [Phase 03-collapsible-dashboard-sections]: CollapsibleContent wired to CSS keyframes via data-[state=open]:animate-collapsible-open Tailwind variant
 - [Phase 03-collapsible-dashboard-sections]: key prop state reset over useEffect: keying DashboardContent by budgetId causes full remount on month change, cleanly resetting openSections without violating react-hooks linter rules
+- [Phase 04-full-app-design-consistency]: Inline SVG paths used for Google and GitHub icons — avoids dependency on external icon library while keeping icons fully styled
+- [Phase 04-full-app-design-consistency]: Auth card accent pattern established: border-t-4 border-t-primary shadow-lg on Card with bg-muted/60 background and favicon.svg logo
