Why does content mean?

Q. 232572. What does content mean? Content meaning depends on pronunciation and context, as word has two main meanings with same spelling. As noun pronounced CON-tent, content means material or substance contained inside something, whether physical container or abstract work, for example contents of box are items inside, content of book is information and ideas, digital content is videos, articles, blogs, podcasts, and social media posts created for online audience, and table of contents lists chapters. This meaning comes from Latin contentus meaning contained, from continere to contain. As adjective pronounced con-TENT, content means satisfied, at peace, fulfilled, and not wanting more, describing emotional state of satisfaction, for example she is content with simple life means she is happy and at peace with what she has. This meaning comes from Latin contentus meaning satisfied. So content means either what is inside or feeling satisfied. Example showing both, The content of the clean room with HEPA filtration in negative pressure room made him content, where first content CON-tent means clean air and equipment inside room, second content con-TENT means satisfied and at peace. So why content means two things is because same Latin root evolved into two senses, one physical containment, one emotional containment of desires, both implying holding enough.
