/*
 * The site's colours are the application's colours, taken from Theming/ThemePalette.cs in the
 * DutyAllocator repository rather than picked to look similar. If the application's palette
 * changes, change these to match: the point of the site looking like the software is that a
 * customer recognises what they are buying when they open it.
 *
 * Light is the default and dark follows the visitor's own system setting, the same way the
 * application follows Windows.
