/*
 * /enterprise — the hero and the industries panel.
 *
 * The hero borrows the B2C landing's fold mechanics (landing-hero.css:
 * .hero, .hero-fold, .hero-cta) and nothing of its look: a full-bleed reel
 * of real work (one clip per industry) under a scrim, a huge LIGHT statement
 * (the site's 340 display weight, set big and tight, two short lines), one
 * line under it and two pills, nothing else. The proof section (enterprise.css)
 * follows right under the fold, on white.
 *
 * The industries' six photographs sit in the right column of the landing's
 * split (landing-splits.css), names only.
