Version 1.4.1

• History page: added date range, medication, and status filters
• History filters include a "Clear" button to reset all filter controls
• Streak calculation now correctly breaks (not continues) when today has doses but none taken
• Refill now adds to existing supply instead of resetting it
• Settings theme switch immediately updates all rendered content
• Preserve user's theme preference when resetting all data
• Guard against stale SVG icon colors after theme change
• Prevent crash on corrupted localStorage by wrapping JSON.parse in try/catch
• Prevent multi-touch collision on dose buttons (simultaneous holds)
• Guard clearHistoryFilters against missing DOM elements
