CHANGELOG

[1.1.0] : Refactor and Optimization

Performance

• IntlCache: Implemented caching for Intl objects. Date formatting no longer creates new instances on every refresh.
• Shared Styles: Used adoptedStyleSheets instead of <style> tags. The browser parses CSS only once.
• Date Math: Removed while loops for year/month calculations. Replaced them with faster O(1) mathematical formulas.

Stability and UI

• Layout Shift (CLS): Fixed content jumping on load. The component now has a default min-height.
• Initialization: Added a non-breaking space (\u00A0) at start. This prevents zero height before the first render.
• TickHub Safety: Iteration over subscribers now uses a copy. An error in one timer will not stop others.

Code Quality

• Private Fields: Changed _variable convention to native private fields #variable. Internal state is now fully protected.
• Attribute Handling: Improved attribute update logic (#isAttrUpdate). This eliminates unnecessary render cycles.
• Auto-restart: The stopped timer restarts automatically if the target date changes to the future.
• Fallback: Added a safety check returning 00:00:00 if formatting results in an empty string.
