<p><strong>Site Grayscale Toggle</strong> lets you turn your entire site grayscale and give visitors a clear on/off switch. It’s built to be <strong>CSP-friendly (no inline JS)</strong> and to avoid a flash-of-unstyled-content by injecting the initial state on the server side.</p>
<p><strong>Features:</strong><br />
– <strong>Grayscale filter site-wide</strong> via <code>html.is-grayscale { filter: grayscale(var(--sgt-level)); }</code>.<br />
– <strong>Intensity control (0–100)</strong> from Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Site Grayscale.<br />
– <strong>Show/Hide floating toggle button</strong> (bottom-right by default).<br />
– <strong>Shortcode</strong>: <code>[grayscale_toggle]</code> to place the switch anywhere (headers, menus, footers, blocks, widgets).<br />
– <strong>Remembers visitor preference</strong> with <code>localStorage</code> across pages.<br />
– <strong>CSP-safe</strong>: no inline JS; initial state added server-side to <code><html></code> to avoid FOUC.<br />
– Lightweight, theme-agnostic; works alongside most caching/CDN plugins.</p>
<p>Use cases include memorial/monochrome modes, accessibility preferences, or design experiments that you want users to control.</p>
