  Icons flow with text.

  The reset above blockifies every svg, which is right for photographs and
  wrong for an icon sitting in a sentence: it takes a line of its own and the
  words drop underneath it. Inside a flex or grid parent nothing shows, which
  is why this went unnoticed — it only bites where an icon shares a plain
  <span>, <p> or <td> with words, which turned out to be 160 places across
  15 pages: every payment option, every service label in the dispatch board
  and the booking tables, the driver's job cards, the dashboard tiles.

  `flex: none` still matters in the flex cases, where an icon must never be
  squashed to make room for a long label. Flex and grid children are
  blockified anyway, so `inline-block` changes nothing there.
