   14px tall themselves — still landing 2.5px apart under
   align-items:center. The real cause turned out to be the site's own
   theme/plugin CSS: a generic `label { margin-bottom: ...; }` rule (from
   a combined/optimized stylesheet) was leaking onto our
   <label class="oda-radio-item"> elements, since we never gave the
   label itself an explicit margin to override it with.
   The 14px spacing between "Standard"/IEC/IEEE is set directly here as
   margin-right (rather than via a separate low-specificity "> * + *"
   selector, which a first attempt at this used — that rule's specificity
   is lower than .oda-radio-item's own, so the margin:0 needed below to
   beat the theme's `label` rule was quietly cancelling it out too,
   collapsing all the spacing). Both are `!important` since the theme's
   reset is external and its own specificity/order relative to ours
   isn't something we control — this way ours always wins regardless. */
