/* ==========================================================================
   NeonForge · Semantic buttons (loaded last)
   --------------------------------------------------------------------------
   Soft stacked pills. Every button has a role that sets three variables:
     --btn-color      fill (solid) or border (outline)
     --btn-color-rgb  the same colour as r, g, b for tints and shadows
     --btn-fg         text on the solid fill
     --btn-text       text/icon colour on a surface (outline, ghost, ring)
   Roles: .btn-primary .btn-success .btn-warning .btn-live .btn-premium
          .btn-info .btn-danger .btn-neutral (the default for a bare .btn)
   Variants: solid (default for a role), .btn-outline, .btn-ghost.
   A bare .btn-outline / .btn-ghost without a role is neutral.
   Palette values live in css/neon.css (--role-*).
