   v1.3.5 — Course + Lesson Hub Rail Alignment Hardening

   The course and lesson archives still mixed two visual alignment systems:
   split search/tool grids and shallower nested card/group padding.  On wide
   screens that made later sections appear to drift left/right even though the
   outer archive shell was centered.  This layer gives both hubs one explicit
   content rail from hero -> search -> results -> cards/groups -> guide.
