 *
 *   A faithful reimplementation of Python's `json.dumps` single-line serialization, used by the
 *   ported `scripts/eval/*.ts` golden/eval builders so their JSONL output is byte-identical to the
 *   Python originals (the committed `data/eval/**` files were written by `json.dumps`).
 *
 *   Two things `JSON.stringify` gets "wrong" relative to Python and that this fixes:
 *
 *   1. **Separators.** Python's default is `(", ", ": ")` — a space after every comma and colon.
 *        `JSON.stringify` is compact (`","` / `":"`). The committed files are spaced, so we match.
 *   2. **`ensure_ascii`.** Python defaults to escaping every non-ASCII codepoint as `\uXXXX` (surrogate
 *        pairs for astral chars). `JSON.stringify` emits raw UTF-8. We replicate Python's default
 *        (`ensureASCII: true`) and allow `ensure_ascii=False` (`ensureASCII: false`).
 *
 *   String escaping of ASCII (quote, backslash, `\n`/`\t`/`\r`/`\b`/`\f`, other control -> `\u00xx`)
 *   is identical between `JSON.stringify` and Python's json, so we delegate per-string base
 *   escaping to `JSON.stringify` and only post-escape the non-ASCII range when `ensureASCII` is
 *   on.
 *
 *   Caveat: JS has a single number type, so a whole-valued float (e.g. an exact `5.0` coordinate)
 *   serializes as `5`, whereas Python's `float(5.0)` -> `"5.0"`. Real-world lat/lon land on exact
 *   integers vanishingly rarely; the builders that emit coordinates accept this edge.
