/**
 * "How it works" — one agent run as a product mock (js/agent-tour.js).
 *
 * Modelled on the app's dark theme (solid-ui tokens, copied as --at-*),
 * the docked Agent column (AgentDockPanel, PlanCard, ReviewCard,
 * ApprovalCard) and the board's ReComp tool node + output container.
 *
 * The mock sits in .agent-tour__window[data-step]. Elements carry
 * data-s="2" or data-s="2-5" (the steps they show in); the script adds
 * .is-off to the rest. The board is drawn at 760×500 and scaled to fit.
