/*
 * The intro (#intro): a film that fills a phone screen; on wider screens it
 * sits in a phone-shaped frame on the night sky. Its colours are fixed in
 * both themes, like the app's stickers, so the film's periwinkle is the
 * card's. Pip is the app's own (pip.js); while it flies, its layers are set
 * frame by frame, so its idle animations are switched off here.
