labvaxe

LabVaxe is a lightweight, modular platform plugin. It adds a LabVaxe menu in wp-admin where you can enable/disable modules independently. 
After activation, all modules are disabled by default until you enable them in LabVaxe.
Included modules:
<h4>SEO & Head Studio</h4>
A “no-bloat” head manager with global settings + per-page overrides: 
* Document title override (via WordPress title filters). 
* Meta description, canonical, robots meta. 
* Open Graph tags (og:title, og:description, og:image, og:url, og:locale, etc.). 
* Twitter Cards tags (twitter:card, twitter:title, twitter:description, twitter:image, etc.). 
* Identity / web-app tags: favicon links, Apple touch icon, manifest URL, theme-color. 
* Per-post metabox on all public post types (except attachments): 
 – SEO title / description / canonical override 
 – Robots mode override (default / index,follow / noindex,follow / noindex,nofollow) 
 – OG/Twitter overrides 
 – Per-page custom JSON-LD (application/ld+json)
Optional extras: 
* Hreflang output from a simple language map. 
* Tracking toggles (opt-in): 
 – Google Analytics 4 (GA4) 
 – Google Tag Manager (GTM) 
 – Meta Pixel 
* Optional GTM/Meta Pixel noscript body output (with automatic wp_footer fallback when themes do not call wp_body_open).
<h4>Head Cleaner</h4>
Performance-focused cleanup for head output and certain core assets: 
* Disable emoji detection scripts/styles. 
* Disable feed links, REST discovery links, oEmbed discovery links. 
* Disable RSD link, shortlink, wp_generator meta. 
* Optional removal of core rel=canonical output (use with care). 
* Optional removal of the core “skip to content” link (accessibility impact—use only if your theme replaces it). 
* Optional cleanup of inline block CSS handles (may affect block styling—use only with a custom theme). 
* Optional disable of WordPress <code>wp_img_tag_add_auto_sizes</code> behavior (can reduce responsive image optimization quality).
Important: Head Cleaner is intentionally “sharp”. If you disable something your theme/site relies on, you can break UX, styling, embeds, feeds, accessibility, or SEO. Enable only what you understand.
<h3>External Services</h3>
LabVaxe itself stores only plugin settings (wp_options) and per-post metadata (postmeta) that you enter in wp-admin.
However, the “SEO & Head Studio” module can load external services if you explicitly enable them. All tracking options are disabled by default. 
A tracker is output only when: 
* “Enable tracking (global)” is enabled 
* the specific tracker is enabled (GA4/GTM/Meta Pixel) 
* the tracker ID is set
When enabled, the plugin may load scripts/iframes from these services:
