/*
 * Waiting / processing states.
 *
 * The signature is the split diagram: one mixed signal on the left fanning out
 * into separate stems on the right — the thing the site actually does, used as
 * the status graphic. Colour encodes separation: periwinkle = still mixed,
 * mint = separated. Stems only light up once the job is genuinely being
 * separated, so the graphic never implies progress we do not have.
