/*
  Boating Hub page — Figma node 18626:19487. Two new reusable pieces:

  1. .content-filter — the white/grey overlap panel that replaces the
     Product Selector on this page (css/style.css's .product-selector is
     a link grid; this is a single-select filter with a Clear action, so
     it gets its own generic component rather than overloading that one).
     Sits in the same .section-transition overlay slot the Product
     Selector uses on Insurance (css/section-transition.css) — same wave
     + overlap mechanics, different content.

  2. .article-grid / .article-card — the 3-column article listing below
     the hero. Generic names (not "boating-hub-*") since any future
     listing page (e.g. a filtered Magazine or Claims Philosophy index)
     can reuse both pieces as-is.
