fix: align Intelligence Digest hero card height with the other 4

The four logo hero cards use a 100px <img>; the Intelligence Digest card
uses an emoji <div class=hero-badge-icon> that was only ~32px tall, so it
rendered shorter. Give .hero-badge-icon a 100px flex-centered box (and
matching 12px bottom margin) so all five cards are the same height.

Cache-bust bumped to ?v=2.9.7.
