/*
 * «آزمون سرعت سایت» — styles for /tools and /tools/speed-test only.
 *
 * A separate stylesheet, not an addition to landing.css, for two reasons: it is
 * loaded by two pages out of a dozen and would otherwise be dead weight on every
 * landing view, and landing.css is a MINIFIED BUILD of landing.src.css — editing
 * it means re-minifying a 43 KB file to add rules that only two pages use.
 *
 * Every colour here comes from the tokens landing.css already defines, so the
 * tool inherits the site's palette instead of starting a second one. The only
 * new axis is the verdict scale (great / good / ok / bad), which needs its own
 * colours because a score has a meaning that the brand gradient does not carry.
