   padded on the side that CARRIES the rule, so a row with no rule is

   began as booktabs' defaults (0.4ex above a rule, 0.65ex below one) and
   were tuned by eye, 2026-09-20: half of the space below moved above, so
   0.725ex above and 0.325ex below, the total unchanged.  The tex target's
   pair is in table.py (TEX_RULE_ABOVE/_BELOW) and differs on purpose -- a
   TeX row and an html row distribute their own height differently around
   the text.  --rulesep is @table's :rulesep, a multiplier, set on the
