/* ============================================
   Card Layout - Shared between Inbox and Archive (KAN-232, KAN-233)
   ============================================

   IMPORTANT: Inbox cards (.message-card-content) and Archive cards
   (.archive-card) must use the same internal structure to maintain
   visual consistency when switching tabs.

   Card structure (identical for both):
   - Row 1: Property (left) + Status/Time/Restore (right)
   - Row 2: Guest name
   - Row 3: Badges (left) + Confirmation/Dates (right)
   - Row 4: Message preview

   Shared classes:
   - .archive-row (base row with flexbox justify-content: space-between)
   - .archive-row-header, .archive-row-context, .archive-row-preview
   - .archive-property, .archive-time, .archive-guest, .archive-header-right
   - .archive-badges, .archive-trip-details
   - .trip-phase-badge, .trip-channel-badge, .trip-dates, .trip-confirmation

   Archive-only (in header row):
   - .archive-status, .btn-unarchive

   When modifying card layout, update BOTH renderInboxView() and
   renderArchiveView() in app.js to keep them in sync.
