/* The media lightbox (issues #866, #1208, #1849): the smallest Military
 * Terminal window, `position: fixed` and outside `.oc-surface`, closed by
 * Esc or a backdrop click. Since #1849 it is a floating window: the body
 * takes its rectangle (left, top, width, height) inline from
 * `MediaLightbox.svelte`, a title strip moves it, the corner grip resizes
 * it, and the image fills the stage keeping its aspect ratio. Moved out of
 * sidebar-help.css so both pages (and the task manager pop-out) load one copy. */
