+/**
+ * The seven cover archetypes a decorated book starts from: the Studio's cover
+ * templates are drawn in them, and the assistant's art direction names one.
+ *
+ * - spine-band: a bleed photo with a coloured band on the binding side.
+ * - poster-pop: a two-tone colour block, a heavy two-line title, a tilted inset photo.
+ * - cutout: a saturated page, organic cut-out shapes around a bordered portrait photo.
+ * - postcard: a pastel page, a landmark drawing, a display serif title and a script line.
+ * - grid-badge: a two by two photo grid with a round title badge at its centre.
+ * - minimal-serif: a white page, a large photo with a hairline, a very large thin serif title.
+ * - stamp-collage: photos in arches and stamps over a checker band, with a round postmark.
