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:

hreflang Flag plugin uses <a href="http://www.w3.org/TR/css3-selectors/#attribute-selectors" title="W3C CSS3 Attribute selectors description" rel="nofollow ugc">css3 selectors</a> to add a flag icon to your links depending on their <a href="http://www.w3.org/TR/html401/struct/links.html#adef-hreflang" title="hreflang attribute description on W3C" rel="nofollow ugc">hreflang attribute</a>.
This is really useful if you regularly link to pages in other languages and you want to inform your visitors about the language of the link target.
It’s even more useful if your own blog is multilingual.

hreflang Flag

Add a flag icon to link corresponding to the hreflang attribute.
