/**
 * SOURCE OF TRUTH KEYWORDS: site-styles, site-reset, nav, buttons, hero, product-picture, pill-mock
 * WHAT:  The reset, the sticky nav, the buttons, the hero and the CSS-drawn product picture (a window being typed into and the recording pill).
 * WHY:   Everything above the fold. The product picture is drawn in CSS rather than shipped as a screenshot so it is sharp at any size, follows the colour scheme, and cannot go stale when the app's look changes.
 * WHERE: Second stylesheet loaded by site/index.html, after tokens.css.
