+# Setup steps:
+#   1. Go to https://developer.ebay.com/my/keys → select your Production app
+#   2. Under "Auth Accepted URL / RuName", create a new entry:
+#      - Callback URL: https://your-domain/api/ebay/callback
+#        (e.g. https://menagerie.circuitforge.tech/snipe/api/ebay/callback)
+#      - Snipe generates the redirect automatically — just register the URL above
+#   3. Copy the RuName value (looks like "YourName-AppName-PRD-xxx-yyy")
+#      and paste it as EBAY_RUNAME below.
+#   4. Set EBAY_OAUTH_REDIRECT_URI to the same HTTPS callback URL.
