/**
 * @djangocfg/ui-tools — page-snapshot
 *
 * Client-side capture engine: walks a live React/Next.js DOM into a
 * compact, token-efficient, redacted CST snapshot for an AI chat that
 * understands the page the user is looking at.
 *
 * Internal to `ui-tools` — consumed by `tools/Chat`. Kept as a folder
 * (not a standalone package) while it has a single consumer; promote to
 * a package only when something outside `ui-tools` needs it.
