/* asset-library.css — right-side asset library panel
 *
 * Mounts as a flex child of hermes' .layout (between .main and the
 * native .rightpanel), so it reflows the chat area instead of overlaying.
 * When the asset library is on, the hermes workspace panel is force-
 * hidden via the `body.al-active` class set by the bootstrap script.
 *
 * Drag the left edge to resize. Click the ✕ to collapse to a 36px rail
 * pinned to the right; click the rail to re-expand to last width.
