/*
 * Colour carries WHO SPOKE and nothing else. Severity gets one column of its own.
 *
 * A timeline that colours by source and by severity at once becomes a rainbow, and a reader
 * scanning it stops being able to tell which dimension a colour meant. Source is the thing being
 * scanned for here — "what did the card do while the SM-DP+ was doing that" — so source gets the
 * colour.
