   DESCENDER SAFETY  (global backstop)
   Fraunces has deep descenders and the italic cut drops further
   still, so display-size headings clip their glyph tails (g, y, p,
   j) unless the content box is given room. Class-level rules with
   higher specificity override this; it exists so any heading that
   is NOT explicitly tuned still renders whole.
