/* christabel.app
   A HumanityZ product, and visibly descended from humanityz.com: Helvetica set tight
   and heavy, hairline rules, square controls, a coloured full stop, a break that opens each
   chapter. But where the studio is ink printed on paper, a fixed halftone screen in four
   process colours, Christabel is the same family in motion. Her identity is the dots she is
   made of: five colours taken from her portrait, loose particles that drift and gather, and
   a night-navy ground. */

/* Display type is the site's own face, drawn for it and built by tools/build-fonts.mjs: a
   heavy, tight, flat-ended grotesque whose dots are round and oversized, like hers. Running
   text and controls stay in the quiet grotesque the page has always used. */
