UI redesign: cards now show series title prominently with color-coded status badges, larger chapter numbers, gradient progress bar, and action buttons styled by state (reading, new chapter, up to date, error, paused, setup).

History import improved: series are now only imported if you have read them consistently in the last 90 days with at least 3 consecutive chapters — eliminates accidental one-off visits.

Bug fix: series imported from history now correctly save the last read chapter URL, so the "Continue reading" button works immediately after import.

Bug fix: popup width expanded to 480px for better readability.

v4.3.1 — Multi-source support & duplicate detection

• Series with multiple reading sources (e.g. Olympus + MangaKakalot) now show a button per site in the card, sorted by most chapters available
• Automatic duplicate detection: if the same manga is tracked on two different sites, the extension alerts you and lets you merge them into one entry
• Notifications persist until manually cleared — unread count badge only shows unattended notifications
• Added support for MangaKakalot (mangakakalot.gg) as a reading source
• Bug fixes: chapter total now saves correctly on first visit, status recalculates immediately after reading
