/* =========================================================
   PALETTE BUILDER
   assets/css/pages/palette-builder.css
   =========================================================
   Core interface styles for the Palette Builder tool.

   Note: .pp-controls, .pp-title, .pp-subtitle were removed — the
   old two-column layout no longer exists in the current JS build.

   Preview-specific styles have been split into:
     preview/desktop-preview.css      (.pp-saas-*, .pp-prv-nat-*)
     preview/mobile-preview.css       (.pp-mobile-*)
     preview/ui-components-preview.css (.pp-ui-play-*, .pp-ui-playground)
     preview/illustration-preview.css  (.pp-illus-*)
     preview/palette-role-preview.css  (.pp-role-prv-*)

   Dynamic state-only rules (active pill, lock-locked,
   color-input overlay) remain in palette-preview.js because
   they depend on JS class toggling and cannot be expressed
   as static selectors without specificity hacks.

   Class reference mirrors CLASS constants in palette-preview.js.
