   Layout: the printed invitation, opened. A centred card first, then a
   left-anchored editorial column that the viewer walks through.
   Light follows the clock of the viewing: ivory daylight at 3:00 PM,
   warming toward sunset at 5:24 PM, ink-blue evening by 7:00 PM.
   The colour tokens below are the 3:00 PM values; js/main.js moves them.
