/* ==========================================================================
   Signic — Registration UI
   Redesigned to mirror the Signic App (app.signic.ir/login) on desktop:
     • black stage, the app column (max-width 430px) centered on desktop and
       full-bleed on phones,
     • the very same design tokens, colors, logo and composition as the app.
   Pure HTML/CSS redesign. NO logic changes:
     • app.js is untouched.
     • every element id / class / data-* used by the JavaScript is preserved.
