/* llmchat.css - LLM playground column.
 *
 * Uses the dashboard's OWN variables. The first version invented --panel2 with a dark fallback,
 * and since this console is a light theme the fallback applied: #171a21 panels under --ink text,
 * i.e. black on black. Every colour below resolves to a variable that actually exists in
 * styles.css :root, and text colour is stated rather than inherited.
