/* ===========================================================================
   Pixel Chatting Hub — Design System v2  "Signal"
   ---------------------------------------------------------------------------
   A premium, agency-grade CRM surface tuned to the OnlyFans ecosystem.
   One signature hue: OnlyFans cyan (#00AFF0). Lightness + a cool neutral
   ladder do the structural work. Two fully-built themes:

     • LIGHT  (default)  — clean, editorial, white cards on a cool canvas.
     • DARK   ([data-theme="dark"]) — deep cool slate, cyan glows.

   Theming is token-driven. Every component reads semantic tokens; the dark
   theme only re-points the value-bearing tokens, so it all swaps in one place.
   Legacy/poetic aliases (--ember, --char, --candle, --dust, --blue …) are kept
   and mapped onto the new tokens so existing view JS keeps working untouched.
