* Removes HTML tags from translatable strings. Uses `sprintf` with placeholder and translators comment.
* Spells out "OG" to "Open Graph" to help translators.
* Adds `@since` param to new filters.
* Improves comments for code standards and consistency.
* Improves readability by making multiple args multiline.
* Micro-optimizations to avoid unnecessary variable assignments.
