/* Theme Milkdown Crepe to blend into the app's translucent "glass" surfaces.
 * Crepe's frame-dark theme is a grayscale palette driven by --crepe-* custom
 * properties; we override those to white-on-transparent with a blue accent so
 * the editor (and the read-only display, which uses the same engine) sits on
 * top of the existing card instead of painting its own opaque background.
 *
 * The floating menus (slash menu, selection toolbar, link tooltip) are portaled
 * to <body>, OUTSIDE .milkdown — so the variables must be declared on those
 * selectors too, otherwise they fall back to transparent and the menu is
 * unreadable over the content behind it. */
