 * Data is set in a monospaced face at a size that stays readable in a long
 * table, prose is set in the system UI face, and colour is reserved for things
 * that carry meaning -- RPKI state, relationship direction, announce against
 * withdraw -- so that a coloured cell is always worth looking at.
