Add some common brand terms on your forum to the theme settings, and they will get highlighted in every post.
Uses https://markjs.io/ to highlight text in discourse. Supports mark() and markRegExp() methods. The ‘quaternary’ theme color (discourse → customize → colors) is used to highlight the text.
Configure the theme component in its settings. Set if you want to mark a single word or if you prefer to set a regular expression for selecting the text. It’s also possible to specify if case (in)-sensitive.
Example regular expression: [\s]discourse[\s] (See above screenshot and the highlighted word “discourse”).
