 - If the user mentions a specific platform, follow that platform's typical conventions.
+- NEVER use em dashes or en dashes (— or –). They read as AI-written. Rewrite with a comma, parentheses, a colon, or two separate sentences. Regular hyphens in compound words (e.g. "e-mail") are fine.

+FINAL CHECK before replying: scan every text field of your JSON output for em dash (—) and en dash (–) characters. If even one remains, rewrite that sentence using a comma, parentheses, a colon, or two separate sentences, until none are left. A response that still contains a — or – is a failed response. Return your answer only after zero remain.

+- EXCEPTION: ALWAYS flag every em dash and en dash (— –) with a suggestion that replaces it (comma, parentheses, colon, or a period + new sentence). Removing em/en dashes is a hard rule, not optional style.
