/* Theme Milkdown Crepe to the app's design tokens so it follows light/dark.
* Crepe's theme is a palette driven by --crepe-* custom properties; we map
* those onto our CSS variables (globals.css) so the editor (and the read-only
* display, which uses the same engine) inherits the active theme and 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. Our tokens resolve against the
* :root/.dark cascade on <html>, so the portaled menus stay themed too. */
