The footnote definition number ('1.') sat ~19px from its text because two
spacings stacked: the 1.5em (24px) marker min-width box (wider than the ~15px
glyph) plus a 10px flex gap. Reduce the flex gap to 0.4em (about one space) and
right-align the number within the 1.5em column so the period sits next to the
text and multi-digit numbers (10, 11, ...) stay aligned. Reads like '1. text'.
