/*
 * The thumb's own diameter is the one measure a slider cannot take from a scale,
 * so it is a property the sheet declares once and the track's inset reads: the
 * TRACK is inset half a thumb at each end, which is what makes the thumb's
 * CENTRE travel exactly the length of the bar it rides. Base UI's default
 * `center` alignment then puts thumb and indicator on that same span with no
 * measuring of our own.
 *
 * The filled half and the thumb's edge take `--lotics-slider-color`, which the
 * call site may repoint at a family token; everything else is the kit's.
