/* V129 collision-free global header
 *
 * The original desktop header remained in one line until 1480px. With seven
 * public links plus QR, guest status, login and registration actions, the
 * content already exceeds the available width on many 15–17 inch laptops and
 * at common browser zoom levels. Between 1481px and 1800px we therefore use the
 * same accessible off-canvas drawer that smaller screens already use.
