## Hero fix, pricing + chrome cleanup

- **Fixed the hero risk-queue rendering bug.** Each interactive risk record showed a blank white box where the agent name should be. Root cause: the per-row inner container used `class="body"`, which collided with the page-level `.body` light-section rule (`background:var(--paper)`), painting the row cream so the near-white name text disappeared. Renamed the row container to `rbody` to remove the collision.
- Removed the "Interactive — click a risk record" hint line at the bottom of the hero.
- Removed the **Enterprise+** pricing tier; pricing is now three tiers, grid switched to 3 columns.
- Removed the top scrolling ticker banner (markup, CSS, keyframes, and the data/render code).
