/* =========================================================
   dd-theme — UI components
   Ported verbatim from the approved mockup styles.css.
   Contract spacing values (non-4-multiples) are preserved as-is
   per UI-SPEC §Spacing exceptions (e.g. course card body padding
   18px 20px 22px, button padding 12px 20px). Do NOT round.

   Adaptation note: the responsive @media blocks below include
   attribute selectors like [style*="grid-template-columns: ..."]
   that targeted inline styles emitted by the React mockup. They
   are ported verbatim and remain valid CSS; PHP templates that
   render those grids (Phase 2) carry the same inline style strings,
   so these rules keep working. The .tab-panel rule (bottom) pairs
   with tabs.js (data-tab-target -> id) and is dd-theme-specific.
