# 029 — Remove unused crates and dependencies

## Summary

Audit `Cargo.toml` and `webapp/package.json` for dependencies that are
declared but not actually used, and remove them.

## Scope

- Check each `[dependencies]`/`[dev-dependencies]` entry in `Cargo.toml`
  against actual usage (e.g. `cargo +nightly udeps`, or grepping for each
  crate's root module name), same for `webapp/package.json` (e.g. `npx
  depcheck`).
- Remove anything unused. If a dependency was added ahead of a specific
  ticket that hasn't landed yet (e.g. `fs-embed` before
  [028](028-fs-embed-static-bundling.md) wires it in), leave it — this ticket
  is about dead weight, not blocking in-flight work.
- Re-run the full test suite and a production webapp build after pruning to
  confirm nothing silently depended on a "removed" package.

## Acceptance criteria

- No dependency remains in either manifest without a corresponding usage in
  the codebase.
- `cargo test` and the webapp build both pass after pruning.

## Depends on

None.
