 1// Package genesis provides a way to store and access dynamic variables that are
 2// set during the genesis or block0 initialization phase. This package
 3// demonstrates an important aspect of p/ packages in Gno: while they are
 4// pure packages, they can have mutable state during initialization (init phase)
 5// before becoming read-only.
 6//
 7// Future improvements:
 8// When Gno supports something similar to "go build -X", this package could be
 9// enhanced to accept variables from the CLI or environment variables (e.g., in
10// gnodev context). For now, it only supports initialization-time operations
11// that make sense at the beginning of the system's lifecycle.
