/* ==========================================================================
   ARKDOX THEME LAYER  (additive: your existing page styles are untouched)

   How it works
   - "Classic" is your current design. It is simply "no skin": nothing here
     applies to it.
   - Every extra theme is switched on by <html data-skin="NAME">. Each theme
     only re-declares the colour/shape variables your pages already use, plus a
     small set of component refinements, all prefixed with
     html[data-skin="NAME"] so they can never leak into Classic.
   - Light / dark still works exactly as before (data-theme on <html>).

   Sections
     1. Style picker (the button + panel in the header)
     2. Theme: FOREST, colour tokens (light + dark)
     3. Theme: FOREST, type, shape and components
   To add another theme later: copy section 2, change the values, and add one
   entry to SKINS in arkdox-themes.js.
