/* filter bar
 *
 * Multi-column layout: each .filter-group is atomic (break-inside:avoid)
 * and the browser flows them into columns top-to-bottom, then left-to-
 * right. Small groups (variant, tier, openness, ...) stack inside the
 * same column to fill the vertical space left by tall ones (provider,
 * family, license). column-width gives the minimum column width; the
 * browser fits as many as the bar width allows.
