/* site/playground/playground.css — the playground's app shell.
 *
 * Self-contained on purpose: this page is an application surface rather than a
 * document, so it does not load the prose site's stylesheet. Nothing here
 * fetches anything — no @import, no url(), no font host. The page test proves
 * that rather than trusting this comment.
 *
 * ---------------------------------------------------------------------------
 * The one hiding rule
 *
 * A screen is hidden as a WHOLE, and nothing finer than a screen is ever
 * hidden. `.screen[data-visible="no"]` is the only `display: none` in this
 * file, and the test file holds that: no rule may hide a disclosure, a model
 * label, a status line or a figure. The sentence a response attaches to a
 * number is on screen whenever that number is, which is the promise that
 * matters; a stage a reader has not reached yet has no numbers and no
 * sentences to hide.
 *
 * ---------------------------------------------------------------------------
 * The viewport
 *
 * The shell is exactly one viewport tall — header, screen, footer — and the
 * page itself never scrolls. Where a response is longer than its pane (the
 * raw JSON, a long location table) the pane scrolls, not the page, so a
 * screen's control and its result are always both in front of the reader.
