/*!
 * @Rank – CSS Selector & XPath Tester: 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-selxp.
 *
 * The highlight colour matched elements get is set from the SCRIPT, not from
 * a rule here — it is applied as an inline style on elements INSIDE the
 * sandboxed preview iframe, a separate document this stylesheet cannot reach
 * (nor would want to: reaching into that frame's own rendering from here
 * would be exactly the kind of leak ADR-008 exists to prevent, just in the
 * other direction).
