Real-time sync between Android and Web for 3D printing (EiPrint Premium launch)

Real-time sync between phone and browser was a constant request from the community. As of this week, every Premium subscriber has it on by default, with nothing to configure.

What changes in practice

• Registrations on any device show up on the other in under 1 second.
• The quote history is single and searchable from any screen.
• Printer profiles are shared between mobile and web.
• It works offline: the queue uploads by itself when the signal returns.

Internally we use CRDTs to resolve conflicts without drama (if you edited the same field in two places, the most recent wins, and both end up with the same final state).
