 * Deliberately plain CSS with no build step. The whole app is three files a
 * person can open and read, which matters more than a framework for something
 * this size — and means a deploy is an rsync rather than a pipeline.
 *
 * The visual brief is a conversation, not a dashboard. Anything that looks like
 * a monitoring product (dense tables, severity badges, gauges) works against
 * the premise that the machine itself is talking.
