/*
 * SoTL Africa — Custom Journal Stylesheet
 * Platform: Open Journal Systems (OJS) 3.1.2.4 / PKP Default Theme
 *
 * HOW TO APPLY:
 *   Dashboard → Settings → Website → Appearance → Advanced
 *   → Upload this file under "Journal Stylesheet (CSS)"
 *
 * NOTE ON THE COVER IMAGE:
 *   A true pop-up lightbox requires JavaScript, which cannot live
 *   in a .css file. This stylesheet instead makes the cover image
 *   open the full-size image in a new browser tab when clicked —
 *   the cleanest "view larger" experience achievable with CSS alone.
 *   The existing OJS anchor around the cover already handles the
 *   click; we just style it to signal that behaviour clearly.
 *
 * SECTIONS:
 *   1.  Design Tokens
 *   2.  Global / Body
 *   3.  Header & Navigation
 *   4.  Homepage — Current Issue block
 *   5.  Full Issue section (hidden)
 *   6.  Articles list
 *   7.  Additional content block
 *   8.  Sidebar
 *   9.  Footer
 *   10. Responsive tweaks
 *   11. Cover image — "View larger" affordance
