/* ============================================================
   /tools — hub-only styles (loaded AFTER redirect-checker.css)
   Page shell (.tools-page, .tools-hero, .product-cta) is inherited
   from redirect-checker.css. This sheet adds:
     - tier filter chips
     - tier sections (Free / Tokens)
     - tier badges + tool-card upgrades
     - hub FAQ block
   Design tokens (--neon-cyan, --neon-magenta, --clip-*) come from
   /static/landing/styles.css via public_base.html.
