/*
 * mspzero.com
 *
 * One stylesheet, no build step, no framework. The site is a handful of
 * server-rendered pages; a toolchain would be more moving parts than the thing
 * it builds.
 *
 * ## The palette, and where each colour is allowed
 *
 * Three surfaces: a deep charcoal for the hero, the managed-hosting panel and
 * the footer; a cool off-white for the body of the page; and white for product
 * cards, which is what makes a card read as an object sitting on the page
 * rather than a region of it.
 *
 * The bright green is a *dark-surface and button* colour and nothing else. It
 * is 14.3:1 against the charcoal and carries dark text at 12.7:1 as a button,
 * but it is 1.2:1 against the off-white — so green text on a light surface uses
 * --accent-dark (5.8:1) instead. There is one rule to remember: bright green
 * never touches a light background as text.
 *
 * Measured pairings: body text 15.6:1, muted text 6.0:1, muted-on-dark 8.6:1,
 * light text on charcoal 18.1:1, accent-dark links 5.8:1.

/*
 * One entrance, once, at first paint — and it moves, it does not hide.
 *
 * The obvious version fades opacity from 0 to 1. Measured in a headless
 * Chromium on this machine, the animation clock never advanced: the hero
 * artwork reported `opacity: 0` indefinitely, which is a blank hero for anybody
 * whose browser behaves the same way. Fill modes do not save it — the failure
 * is the animation not progressing, not the state after it ends.
 *
 * So the animation touches `transform` and nothing else. If the clock freezes,
 * the worst outcome is a block sitting twelve pixels lower than intended, which
 * nobody will ever notice. Content cannot be hidden by an effect that has no
 * way to hide it.
