/**
|
|
* Feature test files import from `src/` through the `@/` alias, never via
|
|
* `../` parent traversal (CLAUDE.md "Key Conventions"). A `../` import in a
|
|
* test file is always reaching across `src/` directories — `@/` keeps those
|
|
* imports stable under file moves and makes the test's dependencies legible.
|
|
*
|
|
* Scoped to feature packages (`packages/<name>/src/`, excluding `core-*`):
|
|
* the convention is part of the feature template's contract. Core packages
|
|
* are generated and governed by their own templates, and tooling packages
|
|
* (turbo/generators, scripts) legitimately use relative paths.
