/* ==========================================================================
   PROTICKS AUS32 / DEF — adbluedef.in
   core.css : tokens, reset, shell

   Built on the PROTICKS group design system established at aus40.in:
   same substrate, same Anton / Barlow / Toxigenesis type, same component
   architecture, same dark mode. The one deliberate difference is the mark
   colour — AUS40 marine carries teal #00738c, AUS32 / DEF carries blue —
   so the two product lines read as siblings rather than as the same page.
