/* ==========================================================================
   Crown Office Supplies — Net 30 cluster cross-links  (cos_net30_cluster_links)

   Loads AFTER cos-home.css, which owns the tokens and the shared primitives
   (.cos-wrap, .cos-section, .cos-section-head, .cos-h2, .cos-eyebrow).
   Nothing here re-declares a token — that is how two pages drift apart.

   WHY THIS EXISTS (Semrush Site Audit, crawl 2026-07-28):
   /quill-net-30-alternative/, /uline-net-30-alternative/,
   /summa-office-supplies-net-30-alternative/ and /net-30-calculator/ each had
   exactly ONE inbound internal link and an internal PageRank (prScore) of 10,
   against 95 for /net30-application/ and /net-30-office-supplies/ — which score
   95 only because they sit in the sitewide footer menu. This block gives the
   four starved pages links from every strong page in the net-30 cluster.

   Anchors are deliberately TEACH anchors ("Quill Net 30 vs Crown"), not CONVERT
   anchors pointing at the application form — the cluster already has plenty of
   those, and mixing the two is what caused the earlier cannibalisation.
