Replace complex multi-platform compositing with simpler spec-compliant implementation: - SocialImageHelper: 1200x630 OG images with solid background, title overlay using TTF fonts (or GD fallback), and site name watermark - SocialImageController: AJAX endpoint with CSRF + ACL checks - Config: enabled toggle, bg/text color, font size, show site name - Content plugin: Generate Social Image button in Share Content panel - Saves to media/com_mokosuitecross/social/ with SHA-256 filename Authored-by: Moko Consulting
