/* Coming-soon page. Brand colors sampled from the logo (grok-proposed-6):
   navy #14304d, teal #00b2bd. Replace once real design direction is set.
   Dark mode follows the OS/browser preference (prefers-color-scheme) —
   there's no manual toggle, and no localStorage-backed override (not
   supported in this environment; revisit if a toggle is ever wanted). */
