 * accent taken from `radio.stations`.`primary_colour`, and the accent is used
 * only for small marks: the wordmark square, links, the live dot, the focus
 * ring. Nothing is a large field of colour, because a large field of colour
 * reads as branding and this site has none.
 *
 * A tenant replacing this file is the expected outcome, not a failure of it.
