1//! Embedded WebUI assets.
2//!
3//! The shell and cookbook pages are embedded at compile time so the binary
4//! serves a complete WebUI regardless of the working directory. The current
5//! bundle paints Scene data and emits Intent values; a live runtime session
6//! bridge can replace or extend these assets without changing this routing
7//! contract.
