 ### Wöchentliche E-Mail-Benachrichtigung (Vorab-Info)
 Sendet wöchentlich (standardmäßig Freitags) eine HTML-Email mit Terminen, die auf Suchbegriffe passen:
 - Sucht nach Begriffen in summary, description und location
+- Optionale Blacklist: Begriffe die ausgeschlossen werden (z.B. `WEEKLY_BLACKLISTWORDS=Ausgeschlossen1,Ausgeschlossen2`)
 - Zeitraum: Samstag bis Freitag der nächsten Woche
 - Subject: Bei 1 Termin "Vorab-Info: Termin am Mo, DD.MM.", bei mehreren "Vorab-Info: X Termine nächste Woche"
 - Tracking via `weekly_notification_log` Tabelle (verhindert Doppelversand)
 - Nur Termine mit Uhrzeit (`all_day=0`), keine Ganztagstermine
 - Keine Email wenn keine Treffer
 - Konfiguration über WEEKLY_* Umgebungsvariablen
-- Funktionen: `parse_weekly_searchwords()`, `get_weekly_events()`, `should_send_weekly()`, `send_weekly_notification()`, `log_weekly_notification()`, `check_and_send_weekly_notification()`
