 * Dev-only sanity checks. Surfaces three classes of caller mistake as
 * `console.warn` so the chart fails loudly in development instead of silently
 * rendering a broken plot:
 *
 * - `xKey` missing on datums (Recharts would draw gaps or break ordering)
 * - `data` not sorted ascending by `xKey` (Recharts assumes an ordered domain)
 * - `series[].key` not present on any datum (line renders empty)
 *
 * Production builds short-circuit before any iteration to avoid the per-render
 * cost on large datasets.
