Accessibility and help using this website.

Use the skip link to reach the main content, clear headings to scan the page and visible keyboard focus to move through controls. Tool results should have text equivalents rather than depending on a map, color or dragging alone.

Reduced-motion preferences are respected for nonessential animation. Text resizing and narrow layouts should keep the main task readable.

Controls need visible labels, understandable units and specific errors. A submission failure should remain visible with entered values preserved when safe.

You can explore guides, checklists and calculations without a mandatory account or contact gate. If an interaction is difficult, use the corresponding text guide or ordinary link to the next step.

A dedicated public accessibility contact will be provided with the approved operating details. Until then, use the available owner-approved contact route when one is shown.

No automated accessibility score by itself certifies that every person can use the site. Practical task testing and correction remain part of its maintenance.
