   link row stops clearing the wordmark long before the layout collapses, and
   the overflow shows up as horizontal page scroll rather than a wrapped nav.
   This value is measured, not guessed — re-run tools/shot.py after adding or
   renaming a nav link and raise it if the reported slack goes negative. */
