Build & Push Docker Image / build (push) Successful in 2m30s
Details

Browse Source 
- use-theme hook: localStorage (toolrate-theme, default system), matchMedia
  change listener, shared singleton listener, sets .dark + color-scheme
- ThemeToggle: lightbulb quick toggle (light/dark) + dropdown (light/dark/system)
- Sidebar footer + mobile header + standalone login page
- inline script in index.html to apply theme pre-render (no FOUC)
- recharts axis ticks use hsl(var(--foreground)) for dark-mode readability
