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