/* ============================================================
   Petropolitan Museum — Site Styles
   Single source of truth for index.html, upload.html, approval.html.

   The homepage (index.html) is the CANONICAL style. Its design system
   lives in the "SHARED DESIGN SYSTEM" section below and is global.

   The two form pages (upload.html, approval.html) are normalized to the
   homepage and scoped under `.form-page` so they can NEVER alter the
   homepage (which still relies on Tailwind for layout). Each form body
   carries `form-page` plus a page class (`upload-page` / `approval-page`)
   for the few page-specific differences (e.g. container width).
