- The play/pause button never swapped icons: app.js set the .hidden property on <svg> elements, which does not reflect to the hidden attribute (that IDL attribute is on HTMLElement, not SVGElement), so the CSS [hidden] rule never applied and both glyphs overlapped. Toggle a .playing class on the button and show/hide the icons via CSS instead. - The Start conversation and mute buttons were pushed off-screen as the transcript grew: the workspace grid had no template-rows, so row 1 auto-sized to the tall transcript and stretched the voice-console beyond the clipped 700px box. Pin the row with grid-template-rows: minmax(0,1fr) and give both grid columns min-height:0 so the transcript (and the inner #messages) scroll instead of expanding the layout.
