/* AgentMem web console.
 *
 * Hand-written because the server's CSP is `default-src 'self'` with no
 * `unsafe-inline`: every rule has to live in this file, since a `style=`
 * attribute is silently dropped by the browser.
 *
 * Layout is an app shell — a permanently dark sidebar next to a themed
 * content column — so the console reads as a tool rather than a document.
 * The sidebar keeps its dark palette in both themes on purpose: it is
 * chrome, not content, and the constant anchor makes the content area's
 * light/dark switch feel deliberate.
