 * Navigation collapse — UI-01
 *
 * The header's contents need about 1091px: logo, seven links, the chapter
 * status line and three utility buttons. The collapse to the hamburger only
 * happened at 768px, so between 769 and 1099 the row was wider than the
 * viewport: "About" sat on top of the PSU wordmark and the search, language
 * and theme buttons were cut off past the right edge. Measured across widths
 * before choosing 1099 — at 1100 the row fits exactly.
 *
 * These are the same declarations as the 768px block; this query just starts
 * them earlier. Below 768 both apply and agree.
