 * style.css — the look of the readiness page.
 *
 * Restrained and technical on purpose. This page is read by someone deciding
 * whether to trust a claim about a physical object, and a design that looks like
 * a product launch makes that harder rather than easier: the readiness report's
 * credibility comes from what it refuses to claim, and the page has to carry the
 * same tone. So: hairline rules, one accent, tabular figures, real whitespace,
 * and no gradient anywhere.
 *
 * THREE CHANNELS CARRY EVERY STATUS — a glyph, a word, and a colour, in that
 * order. Nothing on this page is distinguishable by hue alone. A greyscale print
 * of the page, a photograph of a laptop in a workshop, and a reader with a
 * colour vision deficiency all have to survive "failing" versus "proven", and
 * two shades of a traffic light survive none of them.
