/**
 * Builds the content shown inside a CodeMirror lint tooltip: a leading severity icon followed
 * by the diagnostic message. Returned as a `Diagnostic.renderMessage` factory.
 *
 * @param severity - the diagnostic severity, driving which icon is shown.
 * @param message - the diagnostic message. By default applied via `textContent` (not `innerHTML`),
 * since messages can originate from consumers or external APIs and must not be treated as markup.
 * @param wrapperClass - CSS class applied to the outer flex container, letting each consumer
 * scope its own tooltip styling. The icon element always uses the shared {@link diagnosticIconClass}.
 * @param options - additional rendering options. `dangerouslyRenderHtml`, when `true`, injects the
 * message via `innerHTML` instead of `textContent` — only for **trusted, internally generated**
 * markup (e.g. FilterField's syntax-colored operator list), never for consumer- or API-provided
 * strings.
 * @internal
