Angie writes the CSS for the heading below, but nothing is applied until you approve it.
Ask for a style change in the sidebar. Angie calls propose-css, which renders an MCP App
preview card inside the chat. The CSS only reaches this page when you click Apply to page
in that card — the button calls the apply-css tool directly.
When you are done, ask Angie to close. It calls close-chat, which uses
toggleAngieSidebar(false) and writes the reason onto this page.
