### Visual Highlights of the Usage Statement Page

The dark exhibition-board aesthetic and bold typography give this page a serious, rules-first feel.

- **High-contrast dark background** with neon cyan accents creates a technical, night-mode atmosphere that fits the site's precise, electronic tone.
- **Hanging lines instead of bullets** make each rule feel like a hanging clause, enhancing readability and reinforcing the legal-document feel.
- **Vertical rail tags** on large screens turn each chapter into a distinct panel, echoing the exhibition board concept.
- **Segmented chapter jump control** at the bottom provides quick navigation with clear numbering.

The page balances dense information with generous spacing, keeping the content scannable without losing its authoritative presence.
