As the branch does for older tests: `panic!("…")` instead of
`unreachable!()` in test code (clippy.toml only allows unwrap, expect and
panic there), and the integration tests main added (CLI file I/O, render
gradient text and stroke geometry, SVG export suites) opt out of the
unwrap/expect/panic lints. No test logic changed.

//! Dashes fitted to corners export as the canvas's filled outlines (a dash array can't fit them);

//! exact dashes stay a `stroke-dasharray`. Checked by rendering the exported SVG with resvg.

// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
