/*
  BoundBio — 3D molecular structure viewer styles
  =====================================================
  Pairs with design-system/molecule-viewer.js. Same modal language as
  design-system/intro-popup.css (backdrop scrim, white card, 22px-ish
  radius, no new color introduced) — deliberately not shared classes,
  since the two components have nothing else in common (this one has no
  once-per-visitor logic, no MailerLite dependency), but a viewer reading
  this file right after that one should recognize the pattern immediately.
