   The topic tables now stay in the text column with FIXED column shares: Topic and Payload get
   the width they need (a topic may wrap only at the <wbr> after each "/", a schema name never
   wraps), Direction and QoS share one narrow column, and Notes wraps onto more lines instead.
   Shares come from measured widths: 21 of 28 topics fit 30% of 772px on one line, the longest
   schema name (firmware-response, 142px at 12.5px) fits 23% as long as the table is ≥ 740px — so
