Some records in * the wild have a `theme` object missing `$type`, which makes * `validateRecord` reject the entire publication — dropping it from the index. * * Strip a malformed (no-`$type`) theme so the rest of the record can still be * validated and indexed. Returns the record unchanged when there's nothing to * strip, and never mutates the input. */export function stripThemeWithoutType<T>(record: T): T { if (record && typeof record === "object" && "theme" in record) { const theme = (record as Record<string, unknown>).theme; if (theme && typeof theme === "object" && !("$type" in theme)) { const { theme: _theme, ...rest } = record as Record<string, unknown>; return rest as T; } } return record;}
