/**
 * LogTail — SSR component that renders a <pre> and streams live workflow-run
 * step-log chunks into it via SSE.
 *
 * The initial <pre> is pre-populated with `fallbackLogs` (the DB row's stored
 * logs blob so a viewer with JS disabled, an unsupported browser, or a
 * blocked SSE endpoint still sees whatever was already persisted). Once the
 * inline script connects to `/live-events/workflow-run-<runId>`, it appends
 * step-log chunks as plain escaped text and reloads the page on run-done so
 * the static view takes over.
