<p>Every embedded YouTube video adds weight to your page — external scripts, iframes, tracking pixels — even if the visitor never presses Play. Space Lightplay fixes that.</p>
<p>Drop the block into any post or page, paste a YouTube video URL, and Space Lightplay renders a static preview image with a customizable Play button. The actual iframe is injected only when the visitor clicks. No JavaScript frameworks, no third-party requests until interaction.</p>
<p><strong>Why it matters:</strong></p>
<ul>
<li>Pages with 3–5 embedded videos can save 2–4 MB of initial page weight and dozens of network requests.</li>
<li>Largest Contentful Paint (LCP) and Time to Interactive (TTI) improve because heavy iframes no longer block rendering.</li>
<li>Privacy improves too — no cookies or tracking scripts load until the visitor explicitly chooses to play.</li>
</ul>
<p><strong>What you get:</strong></p>
<ul>
<li>One block, one job — lazy-load YouTube video embeds with zero configuration required.</li>
<li>Custom poster image — upload any image from the Media Library or use the automatic YouTube thumbnail.</li>
<li>Aspect ratio control — 16:9, 4:3, 1:1, 9:16 (vertical/Shorts), or 21:9 cinematic.</li>
<li>Start time — set a starting timecode, or paste a YouTube URL with ?t=… and it fills automatically.</li>
<li>Above-the-fold mode — disables lazy-load on the preview image for hero videos, improving LCP.</li>
<li>Hover prefetch — opens connections to YouTube the instant the cursor lands on the block, so the iframe loads noticeably faster on click. No extra config.</li>
<li>Play button styling — control size, button shape (circle, rounded, square), triangle corner roundness, background color, icon color, and hover states using the native WordPress color picker with full theme palette support.</li>
<li>Block style variations — Minimal, Bold, and Glass presets in one click.</li>
<li>Pulse animation — optional hover effect to draw attention to the Play button.</li>
<li>Thumbnail quality — choose between standard and maximum resolution thumbnails.</li>
<li>Accessible by default — full keyboard navigation, ARIA attributes, optional descriptive title for screen readers, visible focus indicators, RTL support, and prefers-reduced-motion support.</li>
<li>Noscript fallback — visitors without JavaScript get a direct link to the YouTube video (with timecode preserved).</li>
<li>Responsive — chosen aspect ratio adapts to any container width.</li>
<li>Clean uninstall — removing the plugin leaves no options, transients, or database entries behind.</li>
</ul>
<p><strong>For developers:</strong></p>
<p>Space Lightplay uses register_block_type_from_metadata() with a standard block.json manifest. All assets are declared in block.json and enqueued automatically by WordPress. The plugin adds zero global hooks, filters, admin pages, or database entries. Output is a server-rendered block via render.php.</p>

<h3>External services</h3>
<p>This plugin can connect to external video services to display lazy-loaded video thumbnails and metadata.</p>
<h4>YouTube</h4>
<p>When YouTube lazy loading is enabled, the plugin uses YouTube’s public thumbnail CDN to display thumbnail images for YouTube videos. The visitor’s browser requests the thumbnail image from YouTube when a lazy-loaded YouTube placeholder is displayed. The request includes the YouTube video ID in the thumbnail URL and may include normal browser request data such as the visitor’s IP address and user agent.</p>

<h4>Vimeo</h4>
<p>When Vimeo lazy loading is enabled, the plugin optimizes page performance by replacing heavy video players with a lightweight placeholder image. To generate this placeholder, your WordPress server makes a secure background request to Vimeo’s public oEmbed API to fetch the video’s thumbnail URL and, optionally, its title. To minimize external requests and maximize site speed, this data is automatically cached locally using WordPress transients, meaning the server only contacts Vimeo when the metadata isn’t already saved.</p>
<p>During this brief server-to-server connection, your site shares minimal, standard data with Vimeo to fulfill the request. This includes the specific Vimeo video URL (which contains the video ID) and a standard User-Agent string identifying your website’s URL alongside the plugin’s name and version. No personal user data is transmitted, making it a seamless and privacy-conscious way to boost your site’s loading times.</p>
