"""Crop the Amini teardrop mark out of the gold lockup.

The full lockup is three-and-a-half times as wide as it is tall. In a
header that already carries an eleven-item nav there is no width for it,
and shrinking it far enough to fit made the "Materials Trading" line
about four pixels tall - present, but unreadable, which is worse than
absent. The mark alone is nearly square, so it fits at a size where it
actually reads. The full lockup still runs in the footer and the mobile
drawer.

The cut is found rather than hard-coded: walk the columns from the left
and stop at the first run of blank ones wide enough to be the gap
between the mark and the wordmark.
