<summary>Semantic HTML Architecture</summary>
<div>
Web accessibility ensures that websites work for people with disabilities. Native HTML elements provide
accessibility features automatically, following established web standards.
The HTML5 details/summary pattern provides declarative progressive disclosure without JavaScript dependencies.
Browser engines handle state management, accessibility, and user interaction patterns according to platform
conventions.

<summary>Progressive Enhancement Benefits</summary>
<div>
Start with functional HTML, enhance with CSS, add JavaScript where needed. This ensures your content works
across all devices and abilities.
Starting with functional HTML ensures graceful degradation across all environments. CSS and JavaScript become
enhancement layers rather than functional requirements, improving reliability and reducing technical debt.

Native elements eliminate bundle size overhead, reduce runtime memory consumption, and leverage browser

<h3>Embrace Built-in Web Components</h3>

user experience. These elements represent years of browser engineering and web standards development.</p>
<h3>Platform-First Development</h3>
<p>Native HTML elements represent years of browser engineering, accessibility research, and web standards evolution.
They provide robust functionality with minimal implementation overhead and maximum compatibility.</p>
<p><strong>The approach:</strong></p>
<p><strong>The Progressive Enhancement Approach:</strong></p>
<ul style="text-align: left; max-width: 600px; margin: 2rem auto;">
<li>Start with semantic HTML that works for everyone</li>
<li>Enhance with CSS for visual design</li>
<li>Add JavaScript progressively where truly needed</li>
<li>Build with semantic HTML that functions universally</li>
<li>Enhance visual design through CSS without breaking functionality</li>
<li>Layer JavaScript for complex interactions where native capabilities are insufficient</li>
</ul>
<p>Build with the platform, not against it. <strong>Your users will thank you.</strong></p>
<p>Leverage browser engines rather than reimplementing their functionality. <strong>Your codebase will be more
maintainable, your users will have better experiences.</strong></p>

"The most elegant code leverages existing solutions. Native HTML elements provide decades of accessibility research
