/* RIR Transfer Monitor UI.
 *
 * Read: the public register of internet address space, set like an
 * engineering datasheet. Paper and ink, hairline rules, a heavier rule over
 * every section, square corners everywhere. IBM Plex Sans (condensed for
 * headings) and IBM Plex Mono for every resource, date and figure.
 *
 * The one device: the register map (.regmap), a prefix or AS number drawn as
 * its bits, network bits filled. It leads the overview and heads every
 * resource page, and nowhere else.
 *
 * Color rule: the interface is ink on paper; selection and emphasis invert
 * (ink fill, paper text). Colour belongs to the five registries (charts, the
 * swatch in a registry tag) and to two status inks (warn, danger), nothing else.
 * Motion: color and transform only, under 200ms; the register map steps its
 * bits in once on the overview; nothing moves on keyboard-driven actions.
