/* ==========================================================================
   adstxt-checker.css — Ads.txt Validator (/adstxt-checker/ + /result/)
   Loaded after site.css + inner.css, which supply the reset, the fixed-header
   body offset and the shared chrome. This file carries ONLY the tool itself:

     1. page shell   — hero, file-type toggle, domain form, "why" cards and the
                       result-page title bar. All classes are `atxc-` prefixed
                       because the prototype's names (.hero, .check-form,
                       .explain, .pill-btn) collide with site.css /
                       check-web-vitals.css. Ported from the prototype's
                       shell.css minus its header/footer/nav (the shared SSI
                       chrome replaces those) and minus its global reset.
     2. report widget — verbatim from the prototype's widget.css; fully scoped
                       under `.atx` and self-contained, so it stays embeddable.
