/* bracket.css — knockout bracket: horizontal round columns, CSS connectors,
   match nodes, champion box. Geometry note: every column has the same height
   and slots are flex:1, so a pair's children sit at 25% / 75% of the pair and
   the next round's node at its 50% — connector lines meet exactly.
   Interactions (hover path, zoom, drag) land in step 8. */
