/* CaptFlo operator console.
 *
 * The visual reference is the artifact CaptFlo itself prints: an ArUco marker
 * sheet. Plain-text identifiers, generous quiet zones, square fiducials, and a
 * bar labelled "this line is exactly 100 mm - measure it". A sheet that exists
 * to be measured against, not to look impressive. This surface has the same job:
 * report the true state of the instance without flattering it.
 *
 * Monospace does most of the work. That is partly honesty for an operator
 * console and partly a constraint: this instance must run with no network, so
 * there are no webfonts to load. System stacks only.
 *
 * No build step. One stylesheet, served from the web container.
