+# Straw is a YouTube Android client. Patterns flagged:
+#  - SharedPreferences key constants (KEY_SB_CATS, REQUEST_KEY) — identifier
+#    strings, not credentials
+#  - GOOGLE_API_KEY in PoTokenWebView.kt — the InnerTube public API key
+#    every YouTube client (web, Android, iOS, NewPipe, all forks) ships
+#    hardcoded. Public-by-design; YouTube enforces auth via other channels
+#    (visitor data, po_token).
