/* ============================================================
   bighand99.live — Bansal Exchange access guide.
   Shared theme only: tokens, header, access card, support strip,
   footer, SEO box, WhatsApp float, shared content furniture.
   Page-unique rules live in each page's inline <style>.

   Look: the owner-supplied Bansal Exchange sign-in screen — deep
   navy body, navy-teal gradient panel, white card, solid teal
   buttons. Accent here is aqua (bighand99.bet uses gold, .app
   uses amber) so the domains do not render as the same site.
