/*
 * Looseleaf, the encyclopedia arena. Plain CSS, no script: the page is the level.
 *
 * Rules that come from the game engine, so nobody "fixes" them later:
 *  - No text-decoration, text-shadow or gradient text. A destroyed word is hidden by making its glyphs transparent;
 *    an underline or a shadow would stay behind, and gradient text cannot be hidden word by word at all.
 *  - No generated content (list markers, ::before/::after). The engine only sees real nodes, so anything generated
 *    could never be destroyed. Numbers and separators are real text.
 *  - Every box that should shatter has a solid background-color of its own, because its shards are drawn in that
 *    colour. No background images.
 *  - Painted boxes stay well under 60% of the viewport, the engine's limit for a destroyable target. That is why the
 *    infobox is two boxes (plate and facts) that only look like one.
 *  - The page scrolls with the window and nothing is fixed or sticky: the camera is the window's own scroll.
 *  - Pictures are pixel art at 3 CSS px per art pixel. On the desktop layout every image box is an exact multiple
 *    of that (144, 384, 624 px wide), so no pixel is ever stretched unevenly.
