# Integration tests for config loading: full round-trip via `zensical.build()`.
#
# Each test creates a minimal project in a fresh temp directory and invokes
# `zensical.build()`, which calls `Config::new()` on the Rust side. The
# assertions target the *side-effects* of config loading
# (e.g. theme loading: both config formats, success and error cases).
