/* ==========================================================================
   The Karims — shared base styles
   --------------------------------------------------------------------------
   This file IS the design system: tokens, reset, typography and the small set
   of reusable components the brand uses. It is deliberately page-agnostic.

   REUSE: copy this file as-is into the future wedding / RSVP site at
   thekarims.ca. Nothing in here knows about the coming-soon page — anything
   page-specific belongs in its own stylesheet (see css/coming-soon.css).
