/* ==========================================================================
   GS Software - Floating Right-Docked Quick Access Action
   ==========================================================================
   Description:
     A fixed right-anchored floating dock button linking to GS Software.
     Engineered with modular, scoped CSS variables to prevent style bleed.
     Maintains safe clearance from bottom-anchored floating action buttons (FAB).

   Features:
     - Scoped design tokens for seamless maintenance and customization.
     - Anchored flush against the right viewport edge (vertically centered).
     - Visual highlights:
         * Ambient gold and crimson layered box-shadow glow.
         * Inward expanding beacon pulse animation.
         * Specular light-sweep shimmer reflection.
         * Interactive leftward slide and metadata tooltip on desktop hover.
     - Strict transform-origin constraints to eliminate horizontal overflow.
     - Fully responsive across viewports from 320px mobile to 4K displays.
