A nguzunguzu is the guardian figurehead lashed to the prow of a tomoko war canoe. Light hardwood, stained soot-black with dye from the tita nut, then inlaid with shaped nautilus shell bedded in Parinarium-nut putty. One recorded canoe carries 1,053 separate pieces of shell.
The system takes that literally. The page is dead black and light-absorbing. The nacre is the only thing that reflects — it carries the type, the rules, the figure. Rose and green-blue flash keep the shell from flattening into paint. Everything else is empty field.
