/* ============================================================================
   BALAM AI - Pagination Component
   ----------------------------------------------------------------------------
   Global, fully token-driven pagination. Promoted from pages/chat-history.css
   so it renders correctly EVERYWHERE (including the staff /styleguide page,
   which does not load page-scoped CSS).

   - 100% var(--balam-*) tokens — NO hardcoded hex.
   - Theme-aware (light + dark) purely through tokens.
   - Modern pill/rounded controls, ~36-40px touch targets, primary-tint hover,
     filled .active state, reduced-opacity disabled.

   @requires shared-variables.css  (token definitions: --balam-primary,
             --balam-primary-rgb, --balam-card-bg, --balam-card-border,
             --balam-text-*, --balam-gray-*, --balam-radius-*)
