/* ===================================================================
   Course detail page styles (views/courses/show.ejs + course.body_html)
   Extracted from the original course pages — shared by 13 of 14 courses.
   coreldraw uses an older design and gets its own CSS via
   courses.custom_css (see database/schema.sql + seed).

   Scoped under .course-page (the wrapper div in show.ejs) — this block
   was originally written as its own standalone page, so several of its
   selectors (.hero, .hero-stats, .btn-primary, body, a, img, and an
   entire alternate footer design) reused the SAME class/element names
   as the main site and the shared footer partial. Appending it
   unscoped broke the homepage hero, the online-courses hero, every
   button, and the site footer. Scoping everything under .course-page
   fixes that without touching a single course page's own look.
