v0.1.1

Fixed

• Coming back from a link opened in the browser no longer loses your place and no
  longer asks for biometrics again. Three separate faults added up to that:
  • The lock grace period was measured from when you unlocked, not from when you
    left the app, so a minute of ordinary use was enough to re-arm it on every
    return.
  • Locking replaced the content instead of covering it, which released the
    WebView and destroyed the page you were on. The lock is now an opaque
    overlay drawn on top, and it swallows touches since the content is live
    underneath.
  • The WebView kept no state at all, so any activity recreation started over.
    Its navigation history is now saved and restored, guarded by an origin check
    so a history from a previous server address cannot resurface.
