/* NRSG8 — Generalised regulator-Q&A core.

 * 6th distinct aesthetic surface (CLAUDE.md variety rule):

 *   panel.html        utilitarian dashboard
 *   regn0d/web        Swedish-newspaper Q&A

 *   nrs.html          ── IAEA QUIET / DIPLOMATIC SLATE ──
 *
 * Register: calm civic typography, generous whitespace, slate-blue ink
 * on warm-cool ivory. Dual-meaning copy (Nuclear Reactor Safety /
 * Nuclear Regulators Streamliner) gets a quiet but unmissable display.
 * The atomic-orbital decor is slate-on-ivory — not the SSM purple sky.
 *
 * Tokens deliberately distinct from ssmailab.css. NO innerHTML; the
