letter-spacing on the ❚❚ glyph could tighten the character cells but not the visible gap between them on a monospace font — each character keeps its own cell regardless. now two bars drawn via ::before/::after on .is-playing, with exact pixel control over the gap; the ▶ span just hides instead of getting replaced.
