/* Constructor de páginas (pagebuilder.js) — the AI chat on Reportes that builds a page.
 *
 * Reference (CollectUI, 26 oct 2026): "AI chat interaction for a workflow builder" by
 * @timothymaarv — a canvas that fills while the agent works, the conversation as a narrow
 * rail with live step rows, the composer docked at the bottom. Only the frame lives here: the
 * blocks are catalog defaults (`tb-sec-head`, `pm-strip`, `ev-table`, `tb-empty`) and the
 * analyst's own cards (`bb-viz`, agent.css). Everything rides --bb-* tokens. */
