/* =========================================================
   Detector shell for /pt-br/detector-de-ia/ — the paste-box tool UI.


   Lifted verbatim from tools/ai-detector/index.html, which keeps its own
   inline copy. Only pages that link this file are affected, so the live
   tool pages are untouched.

   Every colour/radius/shadow here is a token already defined by
   css/landing.css + css/lp/landing-lp.css. Link this AFTER both.

   Studio contract (ids the tool JS binds to):
     #editor #wordCount #runBtn #resultArea #rpBadge #rpIdle
     #usage #sampleBtn #clearBtn #pasteBtn #toast
