*Fixes*

- Each website's `robots.txt` is now read first and followed. A website whose `robots.txt` disallows the page gets a free row with the new status `robots_disallowed` and its DNS findings; disallowed extra pages are skipped. When `robots.txt` answers with a server error or not at all, the website is skipped as `unreachable`. The `SUMMARY` record counts both.

*Changes*

- Websites are also accepted as `urls`, `url`, `startUrls`, `domains`, `domain`, `targetUrls`, `sites` or `website`, so inputs from AI agents and scripts work without changes.

##### 2026-09-27

*Features*

- First version: technologies of any website from 7,628 fingerprints, matched in the page, its Google Tag Manager containers and the domain's DNS records, with the evidence for every finding and change tracking between runs.
