/* =========================================================================
   PVA Free Training — Social Media Management VA: Beginner Foundations
   Shared design system

   Palette follows the established PVA Free Training system:
   deep forest green + secondary sage green + warm kraft-paper neutrals,
   with a folder-tab / stamp motif for navigation and completion states.

   This pathway uses the established system WITHOUT the cartoon/avatar
   treatment used elsewhere — a quieter, more professional variant, per
   the SMM training brief's visual-direction note.
