<p class="docs-lead">Themes control how your Bulkhead OS site looks. Install a theme addon to change colors, typography, and layout — without touching your content.</p>

<h2 id="how-themes-work">How Themes Work</h2>
<p>Themes are <strong>safe by design</strong>. They can only change visual properties — colors, fonts, spacing, and layout style. They cannot:</p>
<ul>
<li>Access your content data</li>
<li>Run JavaScript on your pages</li>
<li>Modify your site's behavior</li>
</ul>
<p>This means you can install, swap, or remove themes without any risk to your content or site functionality.</p>

<h2 id="installing">Installing a Theme</h2>
<ol>
<li>Open <strong>Workspace Settings → Addons</strong></li>
<li>Browse the Theme Library</li>
<li>Click <strong>Install</strong> on the theme you want</li>
<li>Your site updates immediately — no restart needed</li>
</ol>

<p><strong>Switching themes:</strong> You can have multiple themes installed but only one active at a time. Switching is instant and non-destructive.</p>
