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