/* Live Railway Trains UK — "Signal Box" theme
 *
 * The look borrows from two things every British rail traveller knows:
 * the illuminated track diagrams of signalling centres (ink-navy panels,
 * lit routes, red/amber/green aspects) and amber dot-matrix platform
 * displays (the Doto face). Tokens first; every colour below uses them.
