29 * Maps a real `match.stats` (from `matches.get()`/`matches.subscribe()`)
30 * to Stats List's entries: a plain array, one row per available stat. If
31 * the SDK's shape changes, this fails to compile.
32 *
33 * MatchStats is a discriminated union per sport, so this switches on
34 * `stats.sport`. Every branch is covered, but four sports
35 * (american football, baseball, ice hockey, handball) currently have no
36 * comparable home/away stats in the protocol beyond score and clock
37 * (already shown elsewhere, e.g. Match Highlight), so those return an
38 * empty array rather than padding the list with fields that don't exist.
39 * Tennis's current-game points ("15"/"40"/"AD") aren't included: text,
40 * not a number, so there's no meaningful bar for it.
