2 * Blockenberg AI Agent
3 *
4 * A chat panel in the block editor that builds and edits pages with Blockenberg
5 * blocks. The model runs an agent loop: it searches the block catalog, reads
6 * block schemas, then inserts / updates / removes blocks through the editor's
7 * own data store, so every change is a normal editor change (undo works).
8 *
9 * The OpenRouter key lives on the server — this file only talks to
10 * /wp-json/blockenberg/v1/ai/*.
