/* ---------- Nib — Fountain pens & inks 144 (store) ----------
   THE STRUCTURAL MOVE: the page alternates contained / full-bleed the whole way
   down, and the SAME narrow centred text-only block is used TWICE — once before
   the eight-up grid and once after the banner — as the spacer between the two
   merchandise runs. Every band that is not a product grid runs edge to edge, so
   the two contained grids read as islands with big empty gutters at both ends.
   Indigo lands in exactly three places — the hero slab, the banner link and the
   short rule under the overlay heading — and everything else is paper, ink and
   one warm-grey hairline under each section heading. Tiles carry no ground and
   no border at all: the product photographs sit straight on the paper. */
