 * Consent banner and cookie-settings dialog in the house identity.

 * Text styling comes from the type roles on the markup (.t-h4, .t-body, .t-ui,
 * .t-small, .t-num); this file sets layout, surfaces and control states.
 * Accept and Reject are the same quiet button on purpose: neither is favoured.
 * Nothing here animates an entrance; the only motion is the button response,
