/* ---- Phone Layout: Sidebar Drawer Overlay ---- */

/* On phone, the sidebar is a full-width drawer that slides over the chat.
	It covers the full viewport below the mobile top bar; the top bar's
	sidebar toggle button remains visible and is used to dismiss it.

	The drawer slides in/out with a transition (not a keyframe animation) so
	that interrupted toggles retarget smoothly from the current position
	rather than restarting. The split-view wrapper toggles `display: none`
	via a `.visible` class; `transition-behavior: allow-discrete` defers
	the discrete `display` change until the slide-out completes, and
	`@starting-style` provides the offscreen origin for the slide-in. */
