Start by auditing the heading structure across the Contacts app's pages, modal windows, and sidebars, using the reported accessibility concerns as the checklist. Compare heading levels and markup with the information structure, including cases where headings are skipped, missing, or used for non-heading content. Done means the affected views have a logical, complete heading hierarchy.
