firstLearnerLevel

firstLearnerLevel(
entries: readonly CourseCatalogEntry[],
): { level: LearnerCardLevel; lessonRuntimes: LessonProgressSlice[] } | null
The level a learner card names — the first level course, never a reference course — and its lessons, which the card's progress line counts.
Parameters
- entries: readonly CourseCatalogEntry[]
  The catalog entries, in sequence order
Returns { level: LearnerCardLevel; lessonRuntimes: LessonProgressSlice[] } | null
The first level, or null when the catalog holds no level course
