[INFO] [stdout] Feature: rtb-config — typed, layered configuration
[INFO] [stdout]   Scenario: S1 — minimal config from an embedded default
[INFO] [stdout]    ✔  Given an embedded default YAML "port: 8080"
[INFO] [stdout]    ✔  When I build a Config typed as PortOnly
[INFO] [stdout]    ✔  Then the current snapshot's port is 8080
[INFO] [stdout]   Scenario: S2 — env overrides file overrides embedded
[INFO] [stdout]    ✔  Given an embedded default YAML "port: 8080"
[INFO] [stdout]    ✔  And a user file with content "port: 9090"
[INFO] [stdout]    ✔  And an environment variable "RTBCFG_BDD_PORT" set to "9999"
[INFO] [stdout]    ✔  When I build a Config with prefix "RTBCFG_BDD_" typed as PortOnly
[INFO] [stdout]    ✔  Then the current snapshot's port is 9999
[INFO] [stdout]   Scenario: S3 — missing required field surfaces a helpful diagnostic
[INFO] [stdout]    ✔  Given an embedded default YAML "other: x"
[INFO] [stdout]    ✔  When I build a Config typed as RequiresName and capture the error
[INFO] [stdout]    ✔  Then the error is a Parse variant
[INFO] [stdout]    ✔  And the error message mentions "name"
[INFO] [stdout]   Scenario: S4 — reload picks up updated file contents
[INFO] [stdout]    ✔  Given a user file with content "port: 1111"
[INFO] [stdout]    ✔  When I build a Config typed as PortOnly
[INFO] [stdout]    ✔  And I rewrite the user file to "port: 2222"
[INFO] [stdout]    ✔  And I reload the config
[INFO] [stdout]    ✔  Then the current snapshot's port is 2222
[INFO] [stdout]   Scenario: S5 — Config without a type parameter resolves to Config<()>
[INFO] [stdout]    ✔  Given a default Config with no type parameter
[INFO] [stdout]    ✔  Then the snapshot is the unit value
[INFO] [stdout]   Scenario: S6 — env prefix handles nested keys
[INFO] [stdout]    ✔  Given an embedded default YAML "http:\n  port: 1"
[INFO] [stdout]    ✔  And an environment variable "RTBCFG_BDD_NESTED_HTTP_PORT" set to "4242"
[INFO] [stdout]    ✔  When I build a Config with prefix "RTBCFG_BDD_NESTED_" typed as HttpOnly
[INFO] [stdout]    ✔  Then the nested http port is 4242
