Summary:
  duck-duck-go webbrowser and  `green pass PDF wallet` at android
  webserver at FBX


The problem was my fear for doing duplicate work.
The solution was "Just do it"


Through the F-droid app could I not find "sufficientlysecure viewer".
But I could `Green Pass PDF Wallet` (
 https://f-droid.org/en/packages/com.michaeltroger.gruenerpass/ )
After installation of that PDF app I entered in duck-duck-go

   http://fbx.redacted.lan/f


(first attempt got me "search result, second attempt did visit
my webserver)

Downloaded the ticket.pdf

Opent `Greenpass`. Greenpass did see ticket.pdf  I could open the
ticket.

Took the admissionticket to entrance of venue.
The QR-code from the PDF was accepted.

Didn't see any of the million ways of how this could fail,
did learn that "it works", sharing the expirence with you.
