Submit URL to Brave
Input
url requiredThe absolute URL to submit for re-fetching, e.g. 'https://reduck.ai/pricing'. Brave validates it and rejects anything it doesn't parse as a URL (returned as accepted:false, not an error). One URL per call — the form takes exactly one.
Output
url requiredThe URL that was submitted, echoed back from the args.
detail requiredThe panel's explanatory line, verbatim ('Thank you for your submission.' / 'Please insert a valid URL.'). This is where Brave states WHY a submission was rejected. null when the panel has no detail row — kept nullable because only the success and invalid-URL variants have been observed.
heading requiredThe outcome panel's heading, verbatim as rendered ('Success' / 'Error'). Localized by Brave, so branch on `accepted` instead. Required and non-empty on purpose: Brave shows a 'Verifying you're a human being' step in the SAME panel before deciding, and that intermediate state has no heading — so a missing one means the script read the panel before the verdict existed, which must fail loudly rather than validate as a successful submission.
accepted requiredWhether Brave accepted the submission: true = the success panel, false = the error panel (e.g. a malformed URL). Read off the panel's own `error` class, not its wording, so it survives localization. Acceptance is a queued re-fetch request only — it carries no promise that the page gets crawled, indexed or ranked.
