+ * Extract the payload of an SSE `data:` field.
+ *
+ * The WHATWG EventSource spec treats the space after the colon as optional
+ * and strips at most one leading U+0020. Older AxonHub (0.9) and some
+ * intranet OpenAI-compat proxies emit `data:{json}` with no space, which
+ * a `data: ` prefix check silently drops (issue #3020).
+ *
+ * @param {unknown} line
+ * @returns {string | null}
