/* ═══════════════════════════════════════════════════════════════════════════
   NEXT DOOR — premium UI system for the lead popup + AI concierge.

   One shared visual language so both surfaces look identical:
     · near-black panel (#0d0f12) with fine gold line-art
     · gold accent (#c9a227) used sparingly, as a luxury cue
     · white body with icon-prefixed fields
     · black CTA with a hairline gold border
     · trust row, then a quiet reassurance line

   All selectors are namespaced (.ndx-) so nothing can collide with the ported
   Realar theme CSS.
