/*!
 * @Rank – CSS Animation & Easing Builder: the tool's own rules.
 *
 * The palette, header, cards, buttons, notices and toast all come from
 * assets/css/atrank-core.css. Only what is specific to this tool is here, and
 * every rule is anchored on .atrank-anim.
 *
 * .atrank-anim-previewbox itself carries NO animation rule — that comes from
 * #atrank-anim-style, the stylesheet the script owns and rewrites on every
 * change. This file only draws the box's rest appearance and the bezier
 * editor's SVG chrome.
