## What it does

The skill establishes UI rules for secondary selectors such as language and currency. These controls affect the entire product, yet users open them rarely. The agent separates controls that change what data appears (region or tenant) from controls that change how it is presented. It formats preferences into a single row instead of a vertical stack.

Typography stays deliberately subdued. Font size is capped at 13–14px (`--text-sm`) with `--color-text-secondary` and a regular font weight. Languages must appear as endonyms like "Suomi" or "Deutsch". Solitary flags or globes are not allowed. A flag represents a country, not a spoken language.

If a stored preference gates the initial API fetch, the skill requires gating the request on storage hydration. Changes sync across open tabs via the `storage` event. For menus longer than 20 items, an integrated search bar is required. Flag icons must keep explicit equal dimensions to prevent distortion.

## When to use it
- position language and currency switchers in headers without visual clutter
- separate data-filtering selectors from presentation preferences
- format compact locale dropdowns using endonyms
- sync user preferences across open browser tabs

## Example prompts
- Add a language and currency switcher to the header utility strip
- Review our locale dropdown markup against global-toolbar-controls guidelines
- Where should I place region and unit selectors in the layout?

# 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).

Two classes hide in this list. Controls that change what is shown (region, market, tenant) and controls that change how it is presented (language, theme, units). Group them apart. Lay the preferences out as a row, not a stack. A stack grows with every preference and gives a personal setting the same weight as the control that picks the data. A row absorbs the next preference at no cost to height.

## Where to Place Them

### Header utility strip
A secondary row above or within the main header, right-aligned. Common on e-commerce and international sites.

```
[Logo]                    [EN | EUR | 🌍]  [Account]  [Cart]
────────────────────────────────────────────────────────────
[Main navigation]
```

### Header right — compact
