/* The ground floor: everything below the pinned stage.
 *
 * The stage is the pitch and stays theatrical. This is the workshop, so it
 * changes register deliberately — smaller headings, a visible label column,
 * real product captures, and status words that mean what they say. Colour here
 * is information, not decoration: each capability, each connected tool and each
 * bot carries the identity colour it has in the product.
 *
 * Tokens come from studio.css, so both appearances are covered by one set of
 * rules. Only the identity colours are declared here.
