           Earlier we reserved ~96px on the RIGHT of both card blocks to mirror the Featured

           hid it); on narrow screens the column fills the viewport and the left margin (2rem)
           looked cramped vs the ~96px on the right. Fix: drop the right-only reservation so
           both blocks fill the column symmetrically (left margin == right margin; left edge
           stays at 32/148, aligned with the header), and overlay the Featured next arrow on
           the right edge — the prev "‹" arrow is already an overlay — so the Featured cards
           also fill the full width instead of leaving flex space for the arrow. */
