/* home.css — V4 homepage: editorial hero with real-product composition,
   Featured comparisons (3, editorial panels), Explore categories (8,
   compact nav grid), Buying guides (3, editorial), Deals (4, commerce
   cards via the .deal-card--home modifier of components.css .deal-card),
   Trust band (single dark section), plus the full comparisons directory.
   Layout contract (Phase C): every homepage section is a full-bleed
   <section class="sec"> band -- tinted backgrounds honestly reach the
   viewport edges -- and each band carries its own inner <div class="wrap">
   (see base.html.j2). The former "FINAL POLISH PASS" override layer has
   been folded into the base rules below; there is no second declaration
   block for the same selector in this file. */
