/**
 * Self-contained HTML reporter for `pnpm rudder ai:eval --html`
 * (#A5 Phase 5). Renders one or more {@link SuiteReport}s into a
 * single HTML string with inline styles and minimal vanilla JS for
 * row expand/collapse — no framework deps, no external assets, safe
 * to paste into a PR comment or open offline.
 *
 * Defensive HTML-escape on every piece of user content (suite name,
 * case name, input, response, metadata). Long responses get a
 * `<pre>` block with `white-space: pre-wrap` so output stays
 * scannable without a horizontal scroll.
