Pull request overview

This PR modernizes the LanguageSelector component stories by converting them from render-based stories with wrapper components to an args-based pattern that integrates with Storybook's controls. The changes include adding default args and comprehensive argTypes with descriptions, removing wrapper components, adding individual variant stories (Ghost, Minimal, Small, Large), and replacing hardcoded colors with design tokens for better dark mode support.

Changes:

• Converted stories from render-based pattern with state management wrappers to args-based pattern
• Added default args and comprehensive argTypes with descriptions for better Storybook controls integration
• Replaced hardcoded color classes with design tokens (text-muted-foreground, border-border, bg-card, etc.)

Addressed Copilot Review Comments

Thanks for the thorough review! All three feedback items have been addressed in commit ecab3b2:

1. Default Story State Management (Line 71)

Added LanguageSelectorWithState wrapper component following the same pattern as SelectWithState in Select.stories.tsx. The wrapper:

• Manages internal state with React.useState
• Syncs with Storybook controls via useEffect when the value prop changes
• Forwards the onChange callback for Storybook actions logging

2. AllVariantsComparison State Management (Line 132)

Converted to a named function component AllVariantsComparisonStory that manages independent state for each selector type:

• dropdownValue for LanguageSelector
• nativeValue for LanguageSelectorNative
• inlineValue for LanguageSelectorInline

Each selector now responds to user interactions while staying in sync with Storybook controls.

3. InHeader State Management (Line 151)

Converted to a named function component InHeaderStory with proper state management. The header context demo now correctly updates when users select a language.

---

Testing: All stories now properly respond to both:

• User interactions (clicking a language updates the displayed selection)
• Storybook controls (changing the value control updates the component)

API Signature Mismatch Fixes

The core issue was that onChange receives a Language object (with code, name, flag properties), not just a string. All handlers now properly extract language.code from the object.

Line	Issue	Fix
17	Comment didn't clarify wrapper purpose	Updated to "Story Component Wrapper for State Management (primary Storybook component)"
51	handleChange received string instead of Language	Changed to (language: Language) => { setValue(language.code); onChange?.(language); }
189	LanguageSelector onChange passed setter directly	Changed to (language) => setDropdownValue(language.code)
197	LanguageSelectorNative onChange passed setter directly	Changed to (language) => setNativeValue(language.code)
205	LanguageSelectorInline onChange passed setter directly	Changed to (language) => setInlineValue(language.code)
231	InHeader onChange passed setter directly	Changed to (language) => setValue(language.code)

This ensures the stories correctly match the component's API contract where onChange provides the full Language object for flexibility (consumers can access code, name, or flag as needed).
