+"Čo sa stane pri opakovanom volaní? Ako to opraviť?"
+```python
+def add_item(item, items=[]):
+    items.append(item)
+    return items
+```
+
+„Na čo slúži `if __name__ == "__main__":`?“
+
+Zoznam leadov:
+```python
+leads = [
+    {"name": "Alice", "email": "ALICE@Example.com ", "company": "Acme"},
+    {"name": "Bob", "email": "bob@example.com", "company": "Beta"},
+    {"name": "Unknown", "email": "", "company": "Gamma"},
+    {"name": "Alice 2", "email": "alice@example.com", "company": "Acme"},
+    {"name": "No email"},
+]
+```
+
+Napíš funkciu:
+
+```python
+def prepare_leads(leads):
+    ...
+```
+
+ktorá:
+
+1. odstráni leady bez platného e-mailu (pre účely testu stačí, že obsahuje `@`),
+2. e-mail očistí (`strip`) a prevedie na lowercase,
+3. odstráni duplicity podľa e-mailu – ponechá prvý výskyt,
+4. pridá pole `personalization`, napr. `"Hello Alice, I noticed Acme."`,
+5. vráti nový zoznam a **nemení pôvodný vstupný zoznam**.
