   Deskrune — block library
   Reusable section primitives. Every page should be composed
   of these blocks for layout coherence.

   Inventory (matches BLOCKS.md):
     .block-lead-magnet     — free PDF capture row
     .choose-grid           — "help me choose" decision grid
     .product-grid          — product cards container
     .product-card          — single product card
     .comparison-table      — side-by-side spec table
     .faq-block             — accordion of <details>
     .sticky-buy-bar        — bottom-fixed buy bar (revealed on scroll)
     .section-inner-narrow  — narrow content rail (~720px)
