/* ==========================================================================
   POSSIBER — SHARED STYLESHEET
   Part of the Muzzish design system.

   HOW THIS WORKS (read me before editing):
   The :root block below is the single source of truth for the whole site.
   Change a value there and every page updates. Never hard-code a colour,
   font, or spacing value further down — always use var(--token).

   Tokens marked [MUZZISH] are shared across ALL Muzzish products.
   Tokens marked [POSSIBER] are unique to this product (the accent colour).
