Have you considered a QR code generator that could run on Umbrel locally?
This could be interesting to generate a QR out you want to engrave without the risk of being online, but that your siblings could scan.
Might this be useful?
Some browsers like Chrome and Edge have this feature so you can do it locally.

Other browsers may have extensions for this feature.
If you’re wanting a web app to host on Umbrel, could see if there’s an existing project someone has made that would do this.
Thanks for your reply. I am aware of the web based QR generators.
The idea was regarding using Sharmir Secret Sharing to shard the Seedphrase and then generate QR’s for the shards, that we can print and distribute.
I found SSSS that can work online, but I’m reluctant to upload the shards into a web connected QR code generator.
