//! Story-style regression tests for the thermochemistry plot workflow.
//!
//! Hypotheses:
//! - Clicking `View Plots` should open the temperature-range controls window.
//! - Clicking `Calculate Range` from that window should build a ready plot snapshot.
//! - Invalid temperature ranges should surface a visible error and not leave stale plot data behind.
//! - Real widget interaction should still be enough to select a substance and run a calculation.
//!
//! Expected result:
//! the plot workflow remains a real user-facing path rather than a hidden backend-only contract.
