Module env_override 

Environment-variable config overrides (spec 05 SECTION__KEY).

An env var named SECTION__KEY (double underscore) overrides config[section][key], so SERVER__PORT=4000 sets server.port. Values are coerced to bool/number when they parse, else kept as strings.

Functions

apply_env_overrides

Apply SECTION__KEY=value overrides (as (name, value) pairs) onto config.

from_process_env

Read SECTION__KEY overrides from the process environment.
