Purpose of Update

The current Open Graph (og:) and Twitter metadata generated by UNA often has formatting issues in the description field:

• Missing spaces between sentences when line breaks separate them.
• Run-on words when lowercase letters are followed by uppercase letters without spacing.
• Descriptions cut off abruptly without clear indication.

This update introduces cleaning and normalization logic for titles and descriptions before they are injected into meta tags.

Key Improvements

1. Whitespace normalization

   • Collapses multiple spaces and line breaks into single spaces.
   • Ensures consistent spacing after punctuation (.?!:).

2. Run-on word correction

   • Adds missing spaces between lowercase+uppercase transitions (e.g., wellBeing → well Being).

3. Sentence / bullet separation

   • If multiple sentences or items follow without punctuation, they are separated with a middle dot (•) for clarity.

4. Ellipsis handling

   • If the description is truncated or does not end with punctuation, "..." is appended.
   • If description length exceeds 200 characters (safe for Facebook/WhatsApp preview), it is cut cleanly and suffixed with "...".

5. Title cleaning

   • Strips tags and normalizes whitespace.
   • Ensures Open Graph and Twitter titles are consistent.

6. Generic and neutral fallback

   • If description is truly missing, no hardcoded fallback text is injected.
   • This avoids project-specific branding (so UNA instances remain clean and customizable).

Benefits

• Improved sharing previews on Facebook, Twitter (X), WhatsApp, Telegram, and other platforms.
• Consistent formatting across all UNA apps (Spaces, Events, Groups, Photos, etc.).
• SEO friendliness by ensuring titles and descriptions remain readable and properly spaced.
• Future-proof: Adds safeguards without locking UNA into project-specific slogans.

👉 Recommendation: Replace the existing Facebook / Twitter Open Graph Metadata block in BxDolTemplate.php with the provided drop-in replacement to standardize metadata across UNA installs.
