{
  // affidavit devcontainer
  // ----------------------------------------------------------------------
  // Provides the two toolchains this repo needs:
  //   - Rust NIGHTLY (rust-toolchain.toml pins `channel = "nightly"`), via the
  //     devcontainers `rust` feature driving rustup.
  //   - Node 22 (the self-contained Next.js app in web/ targets Node 22), via
  //     the devcontainers `node` feature.
  //
  // HONEST BUILD NOTE: the `affidavit` crate depends on FIVE sibling path-crates
  // (../clap-noun-verb, ../wasm4pm, ../wasm4pm-compat, ../lsp-max, ../clnrm) plus
  // ../chicago-tdd-tools as a dev-dep. Those are NOT vendored in this repo, so a
  // bare `cargo build` of a lone checkout WILL FAIL — it only succeeds inside the
  // full sibling workspace. The reliably-installable part of this repo is web/,
  // which is why postCreateCommand bootstraps `web/` and not `cargo build`.
  //
  // This file is JSON-with-comments (JSONC), the format devcontainer.json uses.
