/* JARVIS-164 — the agents-page split.
 *
 * The /agents page is three surfaces behind a subnav: the chat-agents
 * workbench (the design work), the registries (skills + MCP servers), and the
 * gateway (identity/policy). This stylesheet carries the chat-agents
 * composition on top of the shared /static/css/style.css tokens (--surface,
 * --border, --accent, .btn, .badge-*); the registries + gateway surfaces reuse
 * the existing admin table/chip classes unchanged.
 *
 * Namespace: .agents-* (page chrome) and .ca-* (chat-agents workbench).
 * The phone drawer below uses the JARVIS-140/141 idiom from base.html's
 * nav drawer: one node, fixed pane, translateX(-100%) → .open, the shared
 * .popout-scrim, and an 800px breakpoint.
