/* ==========================================================================
   SIGNATURE DISHES — 3D coverflow carousel
   --------------------------------------------------------------------------
   This file is SELF-CONTAINED. To remove the slider entirely:
     1. delete this file
     2. delete js/signatures.js
     3. delete the <link>, <script>, and <section class="sig"> in index.html
     4. (optional) delete assets/dishes/

   Everything is namespaced under .sig-* so it won't collide with the
   rest of the site. CSS variables are scoped INSIDE .sig (not :root)
   so they don't leak to other components.
