/*
 * The project pop-up: a project card ("project-card", and the footer's Impressum/Datenschutz links)
 * opens its page in a panel on the right, an iframe of the page with ?project_overlay=1 (script.js).
 * The page behind stays visible in a strip on the left, where the close button sits; on phones the
 * panel takes the whole screen and the button sits top right. Clicking the strip closes it too.
 *
 * The pop-up is added to <body>, outside the page's container, so its sizes follow the window
 * (media queries), not the page.
