Black ink, screentone and white only: reaction tropes (gaan shock, gloom corner, menacing aura, crow silence, petrify), comedy and action (harisen, iai draw, kendo, kyudo, miko), school life (locker letters, zero test, rooftop wind, shared umbrella), town and home (omikuji, shrine prayer, tanabata, floating lantern, alarm smash) and fantasy (yurei, oni, dragon, android, summoning circle, knight, pirate, detective, princess). gen files can now export rim=<px> for a white sticker border, so solid black ink still shows on the black page.
