/* TraceMint control plane — operations console.
 *
 * An operator reads this while something is wrong, at 2am, possibly on a
 * projector in a war room. Three rules follow from that and explain most of
 * what is below.
 *
 * 1. Colour is never the only carrier. Every state that has a colour also has
 *    a word and a shape, because an operator with a colour-vision difference
 *    and an operator on a washed-out beamer need the same answer.
 * 2. No webfont. This console manages environments; it has to render when the
 *    internet does not, so the type stack is the one already on the machine.
 * 3. Density is a feature, but never at the cost of the 200% zoom case — every
 *    dimension here is relative, and every wide region scrolls inside itself
 *    rather than pushing the page sideways.
