/*!
 * @Rank – Colour Contrast Checker: 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-contrast.
 *
 * Three rules here are function rather than decoration:
 *   · the sample block takes its colours from inline styles set by the script
 *     and NOTHING here may override them — it is the one place in the line
 *     where the tool's own palette must keep out of the way, because the point
 *     is to look at the visitor's colours and not at ours;
 *   · the ratio is set in tabular figures at a large size: it is the answer;
 *   · the rule that applies to the chosen size and weight is outlined, because
 *     a table of five verdicts with no indication of which is yours is a table
 *     nobody can act on.
