/* commerce-agent.css: agentic commerce readiness.
 *
 * The design idea: this page is a transcript of a machine trying to do a job on
 * someone's store, so it is built to read like an instrument reading rather than
 * a marketing report. One accent (the platform indigo), semantic colour used
 * only where it carries meaning, and a single dominant element (the agent's
 * attempt) with everything else deliberately quieter beneath it.
 *
 * The first version failed because every block was the same card at the same
 * weight, so nothing led and the eye had nowhere to land.
