How suhas-developer07/printpoint works

Kiosk Server is a campus printing and notes backend. A student authenticates, creates an upload session, uploads to object storage, confirms print settings and price, pays, then retrieves the paid job at a kiosk by token; a kiosk can report completion. Separate journeys support notes publishing and browsing, department-admin management, and print/revenue reporting. The graph reflects the documented layered design and sampled wiring; some route families and integrations are supported by the README rather than fully sampled source.
