+Odin + raylib interactive 3D universe map (DESI data), a Rust + axum API, with Go + Pulumi infra and Gitea Actions CI. A clean `odin build` + `cargo test` + `go test` is the verification step.
 
 ## Commands (root Makefile)
 - Run: `make run` (`odin run src`); Build: `make build` (`odin build src -collection:lib=lib/local -out:bin/desi_explorer`)
 - Web: `make build-web` (Emscripten/WASM -> build/web); Debug: `make build-debug`
-- Test: `make test` (runs `odin test` for src/ and `go test` for infra/); Clean: `make clean`
+- Test: `make test` (runs `odin test` for src/, `go test` for infra/, and `cargo test` for api/); Clean: `make clean`
+- API: `make api-run` (`cargo run` in api/), `make api-test`, `make api-check` (`cargo fmt --check` + `clippy -D warnings`)
 - Setup: `make setup` (submodules + `go mod tidy` in infra/)
 - Infra: `make infra-preview`, `make infra-up`, `make infra-down`, `make infra-refresh` (Pulumi, `--cwd infra`)
 - Renovate: `make renovate-validate` (npx renovate-config-validator)
-- Format Odin with `odinfmt` (config `odinfmt.json`: tabs, width 80)
+- Format Odin with `odinfmt` (config `odinfmt.json`: tabs, width 80); format Rust with `cargo fmt`
 
 ## Layout
 - `src/main.odin` — entrypoint; loop is `update()` → `draw()`; resizable window with an orbital `Camera3D`; point cloud generated procedurally in `make_universe`.
 - `lib/` — third-party Odin deps (submodules / vendored libs). raylib is **not** here: it ships vendored with Odin and is imported as `vendor:raylib`. `lib/local/` is the default `-collection:lib` target and is currently empty.
+- `api/` — Rust + axum backend API that will serve DESI catalog data. `src/lib.rs` exposes `routes`/`models`/`config`; `src/main.rs` is the server entrypoint (binds `API_BIND_ADDR`, default `0.0.0.0:8080`). Crate name is `desi-explorer-api` (lib `desi_explorer_api`); Rust version pinned in `api/rust-toolchain.toml`.
 - `infra/` — Go + Pulumi (`runtime: go`) targeting the on-prem k3s cluster via the default kubeconfig, mirroring the `homelab` repo's pattern. Module name is `desi-explorer-infra`.
-- `.gitea/workflows/` — `ci.yml` (PR: install Odin, `odin test` + build, `go test`) and `release.yml` (tag `v*`: build native + WASM + publish a Gitea release).
+- `.gitea/workflows/` — `ci.yml` (PR: install Odin, Rust, `odin test` + build, `cargo test` + clippy, `go test`) and `release.yml` (tag `v*`: build native + WASM + publish a Gitea release).
 
 ## Conventions
 - Odin code lives in `src/`; external deps go in `lib/` and are wired via `-collection:lib=lib/local` (or a git submodule imported by relative path).
 - Everything is plain `make` — no Taskfile — so CI (Gitea Actions) can call `make` directly.
-- Keep the renderer (src/) and infra (infra/) logically separated; the root Makefile is the only place that ties them together.

 ## Gotchas
 - Odin version is pinned in `.gitea/workflows/*.yml` (`ODIN_VERSION`) and defaults in `scripts/install_odin.sh`; bump both together when tracking a new release.
