/* The cookie consent (app/views/layouts/_cookie_consent.html.erb): the banner of a visitor who has not decided yet and
   the dialog of the settings. Linked EXPLICITLY in layouts/_head, so it reaches every layout, like toast.css. Both lie
   outside any .kl wrapper: the tokens are declared on .kl__consent too, and the buttons and links are the design
   system's (ms-button, ms-link). Every element sets its own margins: above a React application the application's
   resets reach this markup too. Only the z-index is this sheet's own — a token of the mechanism, not of the style. */
