/* ==========================================================================
   IJAESCML — "QUIET HORIZON" SMART JOURNAL THEME  (v5)
   Changes from v4:
   1. ARCHIVES / "Vol. No." LISTING — each issue on the Archives page
      (.obj_issue_summary) is now a proper card/button: cover thumbnail,
      bold volume/issue title in the display serif, a "View Issue" pill
      button, hover lift — matching the same smart-card language as the
      article listings, instead of looking like a plain bullet list.
   2. FONTS/COLOUR — deepened the palette slightly (more ink, less pastel)
      and added a small accent numeral style for "Vol." / "No." so it
      reads as structured, deliberate typography rather than plain text.
   3. BACKGROUND — replaced the golden-hour hillside photo with a muted,
      misty mountain-range image and a cooler, more restrained overlay
      tint (slate + forest, less gold) — closer to how established
      scholarly publishers (IEEE, Springer, Nature-adjacent journals)
      use quiet, serious photography rather than a bright travel photo.
   All prior fixes retained: real flex parent for main+sidebar (with a
   visible divider between them), button-style sidebar links, working
   nav dropdowns, justified body text.
