Devlog 49: Lap Data Export

Plaintext Lap Data Serialization

• formatLapsOutput: a dedicated text formatter that converts active stopwatch data into structured tab-separated values (TSV) suitable for copying.

Async Clipboard Copy Logic

• Implemented an async wrapper using navigator.clipboard.writeText() with built-in error handling (try/catch) and user alerts for unsupported environments or clipboard permission rejections.

Interactive Copy Feedback UI

• Wired copyBtn click events to trigger text copying and dynamically update the button icon (check or error) and theme accent color.
