/* =====================================================================
   NxTGen DeCrypt — button system (loaded last on every page)
   Replaces the flat grey/gold buttons with a "terminal hardware" look:
   machined dark-glass surfaces, a hairline amber edge, a coloured icon
   that lights up on hover, and a soft glow instead of a hard border change.
     PRIMARY   (.primary)               gold, lit from above, sheen sweep on hover
     SECONDARY (.primary.ghost)         dark glass, amber icon, amber glow on hover
     DANGER    (.primary.danger, [data-bi=danger])   red icon + red glow
     GO        ([data-bi=go])           green icon + green glow (start / arm / create)
   Icons are injected by /js/button-icons.js (class .bi). Everything here is
   self-contained (no dependency on main.css) so the landing pages use it too.
