/**
 * Code Blue — an error-log reader, as an OpenStation app.
 *
 * This file is the window: title, size, icon, the title-bar Refresh
 * button, the ⋯-menu Clear row, the state schema, the server actions,
 * and the DATA the browser paints from. The body itself is rendered
 * in the browser by `code-blue.os.ts` — a function of that state and
 * data — so range, search, sort, legend and expand never wait for a
 * request; only reading a different source, refreshing and clearing
 * round-trip. The log model (discovery, tailing, parsing, clearing)
 * lives in `log-reader.php`.
 *
 * @package OpenStation
