/* ============================================================================
   SYNESS — MARKETING SITE
   Built on the Syness Design System (dark-first). The visual language —
   Alegreya Sans, weight + tight tracking, brand purple used sparingly, soft
   corners + one signature 45° cut, crisp hairlines, the ribbon mark as a
   low-opacity watermark — is the DS. Color is the only swappable layer.

   Cascade order: tokens → legacy aliases → base reset → core components →
   marketing/site rules → responsive.
