/*
 * StuderaHP:s header (template-parts/site-header.php, inc/site-header.php).
 *
 * Alla regler har dubblerad rotklass (.shp-header.shp-header, .shp-mnav.shp-mnav)
 * eftersom flera sidmallar sätter global länk- och rubriktypografi med
 * uppskruvad specificitet (samma skäl som i css/site-footer.css).
 *
 * Utan JS öppnas grupperna med :hover/:focus-within. När site-header.js har
 * körts får headern klassen .is-enhanced och då styr .is-open i stället, med
 * fördröjning vid hover.
 *
 * Headern är transparent och ligger ovanpå sidan (position: absolute), så att
 * sidans egen bakgrund syns bakom den. #main-container får en utfyllnad lika
 * hög som headern (--shp-header-h) så att innehållet börjar under den. Heros
 * med margin-top: -100px drar då upp sin bakgrund under headern, inom
 * #main-container (som har overflow: clip). Startsidan reserverar platsen i
 * heron själv och får ingen utfyllnad.
 *
 * Höjden är fast (80 px dator, 64 px mobil) och ändras aldrig efter
 * sidladdning, så headern ger ingen layoutförskjutning.
