/* --- scrim behind the fixed chrome -------------------------------------
 * The nav sits top-left and the name/date block top-right, both fixed, and
 * both have full-width rows scrolling underneath them: the services copy is a
 * right-hand column, and every archive row's title and year pass directly
 * under the date. In the template the two texts simply overlapped and neither
 * could be read. A gradient in the section's own colour separates them, and it
 * only appears where that collision happens — over the carousel photographs
 * the white chrome already reads, and a scrim there would flatten the design.
