• Fix: the "Update profile" button stayed disabled on a fully-filled form after Firefox restored a discarded tab.
• New: duplicate profile names are blocked, with one-tap suggestions (name + birth year / last-4 mobile / village) and a "same person → Update" shortcut.
• New: identity guard — warns before saving one person's form into another person's profile; saving anyway needs a second tap.
• Profile badges show how many fields are saved per form; success message auto-hides; dark-mode readability improved.
• No new permissions. No network. 100% on-device.

Settings → Help → About now shows the version and links to Help, Firefox Add-ons and GitHub.
Example profiles use obvious placeholder Aadhaar / mobile values.
Internal: all UI rendering moved to a safe DOM renderer (0 linter warnings). No functional changes.
