content, following these rules:\n\nEXTRACTION RULES:\n\n1. OTP (One-Time Passcode):\n - Identify standalone alphanumeric codes (letters and/or numbers).\n - Codes should be 4–8 characters long (e.g., \"ABC123\", \"X7K9P2\", \"123456\").\n - May be labeled as: OTP, code, verification code, passcode, PIN, activation code.\n - May be formatted with spaces or dashes (e.g., \"ABC-123\", \"AB CD 12\").\n - Extract only the code itself, removing spaces and dashes.\n\n2. Activation/Verification Links:\n - Extract any URL found in tags.\n - Include URLs from tracking or redirect services (e.g., mandrillapp.com, sendgrid.net).\n - Look for activation-related link text: \"Verify\", \"Activate\", \"Confirm\", \"Complete\", \"Click here\", \"Choose password\".\n - Extract the full URL from the href attribute.\n - If multiple valid links are present, prioritize those with activation-related text as above; otherwise, select the first found.\n\n3. Priority:\n - If both OTP and link are found, return the OTP.\n - If multiple OTPs exist, return the first valid one found.\n - If multiple links exist, prioritize based on activation-related text as above.\n - If neither an OTP nor a link is found, output: No code or activation link found\n\nBegin with a concise checklist (3–6 bullets) of what you will do; keep items conceptual, not implementation-level.\nAfter performing the extraction, validate in 1–2 lines whether the extraction followed the priority and output rules; if not, self-correct and retry.\n\nOutput Format:\n- Output should be a plain string containing only the extracted code or URL, as determined by the above rules.\n- Do not add any extra formatting (no quotes, brackets, or explanations).\n- If nothing is found, output exactly: No code or activation link found\n- If multiple possible OTPs or activation links are present, only output the single item selected by the priority rules.\n- For malformed HTML where links cannot be parsed, treat as if no link is found.`;\n\nconst NO_CODE_FOUND = \"No code or activation link found\";\n\n// Components\ninterface LayoutProps {\n children: any;\n title?: string;\n user?: User;\n}\n\nfunction Layout({ children, title = \"Email Service\", user }: LayoutProps) {\n return (\n \n \n \n \n {title}\n \n \n \n
