Global Toolbar Controls

What Belongs Here

Global controls affect the entire product experience but are not the user's primary task. They are reached occasionally — once per session or less — and should not compete visually with primary navigation or content.

Typical global toolbar controls:

• Currency selector (e-commerce, financial tools)
• Language / locale switcher
• Region or market selector
• Unit system (metric / imperial)
• Theme toggle (light / dark)
• Accessibility preferences (font size, contrast)

These are distinct from user account settings (which live in a profile menu) and from contextual settings (which live adjacent to the feature they affect).
