+// Spreewaldzeit – Datenbankschema
+// SQLite für den MVP. Das Schema ist portabel (Postgres/MySQL).
+//
+// Block-Modell ist bewusst generisch gehalten: `source` speichert,
+// woher ein Block stammt ("manual", "airbnb", "booking", "direct").
+// So kann später ein iCal-Importer die Tabelle befüllen, ohne dass
+// das Schema sich ändern muss.
