I The imprint

The house name, its telephone and its correspondence address. Changing these rewrites every line of the catalogue that names the house, including the tel: and mailto: links, the page title and the structured data.

House name Telephone Email Mark (logo image URL) An https image, or an inline data image. Anything else is ignored.

II The ink

Two colours run this catalogue: the ink it is printed in and the gilt it is tooled with. Every ruled band, plate mount, status mark, button, link and focus ring is derived from them. Text that must stay legible is guarded, not merely tinted.

III The founts

A display fount for the catalogue setting and a text fount for the interface. Shown set, not listed.
