The initial Task 13 pass dropped the back-chevron link above the hero
to satisfy a strict getByRole('link', {name: /Miles Davis/}) matcher
that was finding both the back link and the inline hero-artist link.
Better fix: keep the back affordance users expect, and use matchers
that accept ambiguity — getAllByRole for the hero check, and a
strict '^← …' regex for the back-link assertion.
