🟡 MEDIUM RISK

Suggestion: The Use Case column still mentions 'served via Deno', which is inconsistent with the removal of Deno in favor of Bun throughout the rest of the policy.

3. **`bun install --production --frozen-lockfile` for production deps** - resolved from `package.json` and pinned via `bun.lock`; `--frozen-lockfile` makes a lockfile mismatch a build failure rather than a silent re-resolve

5. **No Python anywhere** - Use Julia for data/batch, Rust for systems

A second packager is permitted only where it is the sole source of a
specific named dependency, documented as such.

Add ReScript to the playground ban table.

The root policy bans both TypeScript and ReScript, but this table only lists TypeScript. A contributor following the playground-local policy can therefore add ReScript despite the repository-wide ban. Add | ReScript | AffineScript |.

ReScript entry to the playground ban table, mapping ReScript to AffineScript
alongside the existing TypeScript-related restrictions.
