1//! IM.6b — the inline-media provider guest world.
2//!
3//! A WASM media provider implements the `media-plugin` world: it exports the
4//! `media` producer (`media-blocks`) and imports the capability-gated
5//! `host-services` a scan might need. This module holds the `bindgen!` for
6//! that world, using the same shared-types trick as every seam before it —
7//! `with:` points `types` + `host-services` at the `plugin` world's generated
8//! modules so a crossed `media-block` is the SAME Rust type the boundary
9//! round-trips.
10//!
11//! **Producer, async.** The guest is called OFF the render path on a trigger
12//! and its result cached; a guest on the render path would be per-frame WASM,
13//! a paramount-#1 violation.
