/* ==========================================================================
   Araçlar — tool pages (araclar/*). Scoped: .tool-*, .brief-*
   Proje briefi: hero (crumbs + h1 + start button) → the tool (eight steps on the
   site's label/body split; output box) → example output (static HTML) → why a brief → tips.
   The tool comes right after the hero so step 01 starts inside the first desktop screen.
   Without JavaScript the form is a plain checklist (.brief-nojs explains);
   proje-briefi.js reveals the buttons and the output.
