// Generate DTS separately to avoid memory issues.
//
// [#4845] The DTS pass runs under an explicit `--max-old-space-size` (see the
// `build` script in package.json). That number is a CEILING V8 is allowed to
// grow to, NOT a reservation — set it above what the machine can actually give
// and V8 simply stops collecting aggressively, grows past physical memory, and
// the kernel OOM-killer takes the process with NO diagnostic output at all
// (`DTS Build start` followed straight by `ELIFECYCLE`). It was 12288 on a
// 16 GB `ubuntu-latest` runner, which is that failure, not a guard against it:
// four CI hits in one morning across PRs that shared no content — including one
// pure-prose patch — and the fourth ejected a PR from the merge queue.
// Keep this comfortably under the runner's physical memory.
