/*
 * Comentarios: panel lateral, hilos, marcadores del lienzo y contador de las
 * miniaturas.
 *
 * El panel sigue las medidas del panel lateral de PowerPoint 2024 (340 px, el
 * token `--ppt-sidepane-w`) y flota sobre el área de trabajo entre la barra de
 * título y la barra de estado, igual que `.shape-format`.
 *
 * Las clases propias llevan el prefijo `comments-` o `comment-`; la única
 * excepción es `.thumb__comments`, que pertenece a la miniatura porque es donde
 * se dibuja el contador.
