 * Configuration for the legacy ChannelFinder HTTP API path prefix.
 *
 * <p>The property {@code channelfinder.legacy.service-root} controls the first path segment of all
 * legacy-API URLs (e.g. {@code ChannelFinder/resources/channels}). Multi-service deployments
 * typically use different roots per service to distinguish paths at a shared reverse proxy.
 *
 * <p>The value is normalized on startup: leading and trailing slashes are stripped, and an empty or
 * blank value reverts to the default {@code ChannelFinder}.
