/*!
 * @Rank – JSON, CSV & YAML Formatter: the tool's own rules.
 *
 * The palette, the header, the cards, the buttons, the notices and the toast
 * all come from assets/css/atrank-core.css. Only what is specific to this tool
 * is here.
 *
 * Every rule is anchored on .atrank-df, the tool's own root class. A bare
 * .atrank-something would reach the host page's markup — the harness fails on
 * it, which is how twelve of them were caught during the merge.
 *
 * Two rules here are function rather than decoration:
 *   · the two boxes are the same height and scroll themselves, so the page does
 *     not grow to the size of whatever somebody pasted;
 *   · both are wrap="off" with a horizontal scrollbar, because a formatter's
 *     whole output is its line structure and soft-wrapping destroys it.
