/// Test Metrics). Returns its own nonce'd `<style>` + `<script>` block, meant to be
/// placed just before `</body>`.
///
/// It defines two globals:
/// * `window.slocToast(msg, {type})` — shows a stacked, auto-dismissing toast in the
///   bottom-right (`type` = `success` | `error` | `info` | `loading`). A `loading`
///   toast stays up until its returned handle's `.dismiss()` is called.
/// * `window.slocExportPdf({html, filename, button})` — the single code path for every
///   "Export PDF" button: greys the button, shows a loading toast, POSTs to
///   `/export/pdf`, triggers the download, then raises a success or error toast and
///   restores the button. Centralising this guarantees identical, obvious feedback
///   everywhere instead of a silent `alert()`-only failure path.
