/*!
 * @Rank – Redirect Rule Generator & 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-redir.
 *
 * Three rules here are function rather than decoration:
 *   · an issue's LEVEL is carried by its left border as well as its colour, so
 *     it survives a client theme that overrides background colours — several do;
 *   · the trace is a plain vertical list, one hop per line, because the thing
 *     somebody needs from a tester is the ORDER the hops happened in, not a
 *     diagram;
 *   · the generated output is monospace and pre-wrapped, never re-flowed, since
 *     it is meant to be copied character-for-character into a real config file.
