Make habitat labels reusable

Species pages are stronger when the core habitat language lives in one reference page.

Keep the zones broad and useful

The goal is reader orientation, not a technical oceanography lesson.

Link deep-sea and coastal pages together

A habitat zones page helps readers move between the site's strongest clusters.
