 * Chat bridge — how the AI drives the user's live page.
 *
 * Two layers:
 *
 * - `bridge/` proper — the command registry, the built-in commands, and
 *   the directive transport (SSE → singleton bus). This is the AI's
 *   control surface over the browser.
 * - `overlay/` — how a `point` directive is drawn: ref resolution,
 *   geometry tracking, and the SVG-mask spotlight.
 *
 * Read-only by default. Commands that would change the user's data
 * (`fill`, `click`) are deliberately stubbed.
