💾 High Memory
Allocates large byte arrays into a static process-level list that is never cleared. Memory accumulates across requests and is never garbage-collected.

byte[] chunks are appended to a static List on the controller class. The list is rooted at the process level so the GC can never collect it — memory grows with every button press and is only released when the process restarts.
