Copy to Clipboard Feedback

Description

When users click a "copy" button, they should receive immediate visual feedback confirming that the content was successfully copied to their clipboard.

Why it matters

• Confirmation: Users need to know their action succeeded before moving on
• Trust: Without feedback, users may click multiple times or doubt the functionality
• Accessibility: Visual feedback helps all users understand the system state
• Reduced errors: Users won't accidentally paste old content thinking the copy failed

When to apply

• Copy buttons for code snippets
• Share links or referral codes
• API keys or tokens
• Any "copy to clipboard" functionality

When not to apply

• When the copied content is immediately used in the same interface (like a paste field)
• Keyboard shortcuts (Cmd/Ctrl+C) - users expect these to work silently
