/*
  Public product site — simrigagent.com landing page.

  Glass theme (no .theme-operator on <body>), so every panel here reads the
  same semantic tokens as the rest of the public site and inherits the
  translucent look automatically. See DESIGN_SYSTEM.md §0.

  Layout-only dimensions (container widths, screenshot aspect ratios, the
  marquee's travel distance) are declared once as --lp-* custom properties
  below rather than sprinkled as literals. They are page geometry, not
  design-system values — there is no token for "how wide is a marketing
  container", and inventing global ones for a single page would be worse.
  Everything that DOES have a token — colour, spacing, radius, shadow, font
  size, breakpoint — uses it.
