   Board selectors

   Four bordered options sharing a single row, in the order they matter:
   the 60s reference board first, the 60s enhanced board next, then the two
   quick checks. The reference board keeps a permanent gold accent, the same one
   the benchmark already uses for its highlighted values.

   The row is allowed to wrap. Four boxes on one line is right on a desktop and
   impossible on a phone: with `nowrap` and an equal basis the four were squeezed
   to about a hundred pixels each on a 420px screen, so the labels truncated to
   "5s quick che" and the sub-labels spilled sideways over their neighbours. A
   basis wide enough to read is what makes the row wrap by itself when there is no
   room, and it still fills a single row wherever four of them do fit. */
