//! Embedded WebUI assets.

//! The shell and cookbook pages are embedded at compile time so the binary
//! serves a complete WebUI regardless of the working directory. The current
//! bundle paints Scene data and emits Intent values; a live runtime session
//! bridge can replace or extend these assets without changing this routing
//! contract.
