   KUTAY OS — pack.html ("Pack your brand")
   A self-contained dark "studio room" inside the app window: finished
   mockup categories, a filterable service catalogue, a process strip, a
   deliverables box, FAQ and a live scope estimate. Only this page loads
   it. Colours are local CSS variables on #packApp (the tool predates the
   shared token system and keeps its own dark "print room" palette), not
   the site-wide tokens — consistent with treating it as one editorial
   room rather than restyling it to match the rest of the shell.
