/* Phase 3K introduced a flex/justify-content:center override here for
   sparse result sets (1-2 products in a 4-5 column grid), reasoning that a
   left-pinned single card looked "lost." Reverted in Phase 3K.1: a
   catalogue grid is not a merchandising rail — the business's explicit
   instruction is that a sparse archive result must occupy the FIRST grid
   position(s) (same start point a 20-product page would use), never
   centered and never stretched. .bholats-product-grid's base rule
   (product-card.css) is plain `display:grid; grid-template-columns:
   repeat(N,1fr)`, which already does the right thing on its own: a single
   item's normal auto-placement lands it in column 1 at its normal card
   width, and unfilled columns simply stay empty to its right — no
   override is needed for archives at all. See
   docs/SPARSE-PRODUCT-GRID-BEHAVIOUR.md. */
