/* Handover's website. Colours from the app (dmx-merge web/launch.html): dark, red = live, green = next.
   Design: Apple's approach translated for the web (the apple-design skill): system type with size-specific
   tracking and leading, translucent chrome, instant press feedback, springs for anything you can touch,
   reduced motion / transparency / more contrast honoured. Spacing in rem so larger text scales the layout. */
