/* Tab Title Tamer, the product site.
 *
 * The "premium dark" direction of the store images (promo/src/promo.css):
 * charcoal ground, orange as an accent, glassy cards, Tabstrip on the
 * headings exactly as in the product. The tab mockups are the same
 * components the images and the demo use, so the site cannot promise a
 * different-looking product than the listing does.
 *
 * One committed theme. Every visual asset the product has (screenshots,
 * the demo, the popup) is dark, and a dark page is where they sit flush.
