/* Free tools hub (/tools).

   Replaces the inline <style> block the page carried while it listed ~16 hand-curated tools.
   At 89 catalogue-driven tools the old image-led two-column card stopped working: 74 cards shared
   one placeholder OG banner cropped to a sliver, and every card repeated the same trust and
   pricing sentences. Those are now stated once at page level, so a card carries only what differs
   between tools — product, name, description, and what it takes in.

   The product filter is CSS-only (hidden radios + :has()) because the page is static SSR
   (ExcludeFromInteractiveRouting) and must stay crawlable. With :has() unsupported every tool
   simply stays visible, which is the pre-filter behaviour. */
