+//! bimr-wasm — browser adapter for the [`bimr-engine`](https://git.rvba.fr/rvba/bimr-engine) eval.
+//!
+//! **Whole-source only**: the adapter exposes exactly one export —
+//! `compile(src)`. There is no session layer, no per-call construction, and
+//! no side queries: Python emits `.bimr` text and calls `compile()` once,
+//! the same path as the CLI. The `.bimr` intermediate is the compatibility
+//! layer; whole-source is the single entry point for the CLI, web Python,
+//! and LLM paths.
+//!
+//! Errors return `{"error": "..."}` JSON strings.
