/*
 * pictogram-builder — turn a tally / data set into a pictogram with
 * a chosen scale (1 icon = 1, 1 icon = 2, etc.). Per-category icon
 * stacks to the right of each label; +/- buttons adjust counts;
 * scale selector changes how many units each icon represents.
 * Half-icons (when count doesn't divide evenly into scale) render
 * via a clip-path so primary pupils see the partial unit.
