/* ==========================================================================
   TokForge site.css  ·  v10 ember design system, shared sub-page layer
   Task #916 phase 2. Companion to the #915 landing (which keeps inline CSS).

   Loaded AFTER each page's own <style> block on purpose: this file owns the
   palette tokens, the chrome and the reading layer, while every page keeps
   its own bespoke component layout untouched.

   Palette sampled from the launch art: ember #F5A623 on ground #07090E.
