/*
 * The back office's look (#961): a plain internal tool in the brand's tokens
 * (shared/design/tokens.json, `theme.scheme`, as web/app/src/styles/tokens.css
 * resolves them, and the accent «Neón»), dark by default and light where the
 * device asks for it. A counting desk: quiet surfaces in steps of one grey,
 * figures aligned, and the accent only on what matters, the latest bucket of
 * a chart and a screen's one primary action. Saira, the brand's face, sets
 * the brand, the headings and the big figures; the system font the rest;
 * ids and technical figures are monospace and muted. Spacing on a 4px scale.
