I'm building a custom WordPress block for testimonials. I want you to write the PHP, JS, and HTML with an a11y-first approach. Assume a screen reader and keyboard-only user. Include screen reader text where appropriate, proper heading levels, semantic structure, and aria labels only if they’re absolutely necessary. Explain any a11y tradeoffs you make. Use WordPress best practices throughout.
