; Air Fortress (U) application-specific RAM aliases - Pass 1
; Generated from every direct zero-page operand in reachable code:
; ref counts are reads/writes, `where` lists the referencing addresses.
; ZpXX names indicate storage with a role not yet unique enough for a behavioral name;
; Pass 2 replaces them with names derived from observed usage.
