/*
 * The BRIDGE. Every bar floats between the level before it and the level after,
 * so it is absolute in BOTH orientations and the axis it does NOT float on has
 * to be pinned: a horizontal bar given only `left`/`width` collapses to its
 * minimum and draws a hairline where a bar was asked for.
 *
 * The connector and the baseline are hairlines in the SAME ink as a table's
 * rules: they join two bars and mark zero, and neither is a third quantity.
 *
 * Every fraction the geometry produces is DATA and arrives as a property, so a
 * consumer can restyle a step without `!important`.
