/* Ask: the launcher, the panel, and the passages.

 * The panel is a reading surface, not a menu. A result carries a real
 * passage rather than a title and a promise, so it is set at the book's own
 * measure and rhythm instead of the tight leading a command palette uses.
 */

/* The panel floats above the page, so it needs an opaque ground of its own.
 * eb-book.css defines surfaces but no page background, and inheriting the
 * theme's would make the panel transparent over the scrim. Three blocks,
 * matching eb-book.css: the default, the system preference, and the
 * explicit toggle in both directions. */
