1//! Platform seams (rust-implementation §Workspace layout).
2//!
3//! M0 carries only what M0 needs: `Clock` and `SecretStore`. Fs/Exec/Http
4//! traits join when the browser milestone makes indirection pay for itself;
5//! until then native crates use std/tokio/reqwest directly behind their own
6//! crate boundaries (the seam is the crate, not yet a trait).
