Description

Make research on how to implement feature with questions showing on phone unlocking. Document requirements and architecure.

To do

• Which app components are needed?
• Which permissions are needed?
• Will the OS kill components? If yes, how to recover them?
• How to show question card overlay? Does it need specific viewmodel? Will this work with Compose layout?
• Document feature architecture in Figma (справочная)

Notes

Most probably, we will need one background service with broadcast receiver. Deeper research needed.

• All questions above are answered
• Architecture is clear and documented
