"""Year-1 (freshman) course catalog used by /seedcourses.

Sources (checked 14 Oct 2026):
  * Courses WITH a code: official DBU course catalog (dbu.edu.et, College of Engineering, Year I).
  * General Biology / General Chemistry: national natural-science freshman list (Jimma / Debark).
  * Social-science-only courses: national common list (University of Gondar). No DBU source found.
  * Courses that natural AND social students both take are stored ONCE (stream "all").
    A file for "English" therefore never needs to be copied into two courses.
