Lets a fixture assert every axe rule it exercises rather than only the CSS-dependent visual ones, which is what the per-component WCAG reports need.
Adds a table-driven Playwright suite covering 1.4.10 Reflow, 1.4.4 Resize Text and 1.4.12 Text Spacing across the assessed components. axe has no rule for any of them, so they were rated Manual on evidence from source review.
