/*
 * Aqtora marketing site — one stylesheet, no imports, no web fonts.
 *
 * Monochrome by rule: ink on paper, one amber and one green reserved for status, nothing else.
 * Both accents are dark enough to keep 4.5:1 against the page background, so status text does not
 * become the one unreadable string on the page. Mobile first; the only breakpoints widen a layout
 * that already works at 320px.
