   Purpose: The ONE shared public Storybook viewer's styling (Section 6/21). Pillar-neutral — uses
            only the site's global theme tokens (--bg/--fg/--muted/--surface/--border/--radius from
            assets/css/themes.css), never a MamaDEX-only or other pillar-specific palette. Responsive
            conventions mirror assets/css/partials/relationship-popup.css (rem-based breakpoints,
            prefers-reduced-motion respected, no nested horizontal scroll).
