/* ============================================================
   FABBRUCCIO: THE CART PAGE

   Layer 3 (section). Enqueued on /cart/ only by the child functions.php
   $sections map (handle `fab-cart`, depends on `fab-tokens`).

   Markup:    templates/page-cart.html -> wp:fabbruccio/cart
   Render:    inc/cart.php
   Behaviour: assets/js/cart.js

   NOT TO BE CONFUSED WITH fab-minicart.css, which is the DRAWER behind
   the nav's CART pill and is sitewide chrome. This file is the cart
   ROUTE. Both are ours now:

     fab-minicart.css  the drawer      ours, top to bottom
     fab-cart.css      the /cart/ page ours, top to bottom  <- this file

   ------------------------------------------------------------
   WHAT THIS REPLACES
   ------------------------------------------------------------
   This file used to be ONE RULE. It countered the weight of the
   parent's `.iw-cart-heading` and stopped, with a header explaining
   that rebuilding /cart/ was "a real design decision ... explicitly NOT
   this pass's job", flagged for the user.

   That decision came back: rebuild it as Fabbruccio's own. So the single
   rule is gone along with the template that made it necessary. There is
   no `.iw-cart-heading` on this route any more (the parent's page-cart.html
   no longer renders at all), and countering a selector that cannot appear
   would be dead CSS pointing at a surface we removed.

   ------------------------------------------------------------
   NO BETA CART TO COPY
   ------------------------------------------------------------
   The design bar has no cart page: beta's nav pill links straight out to
   the checkout host (fabbruccio-v2/index.html:276). So this is composed
   FROM beta's language rather than lifted from a beta component, exactly
   as the mini-cart was, and every value below names the beta rule or the
   token it comes from:

     square corners            beta --btn radius 2px, never the pill
     uppercase + letterspaced  beta .eyebrow / .nav-links / .btn
     Playfair 500 for display  beta h1 / .doc h2, never >= 700
     gold as accent only       beta uses --gold for links + rules, never fills
     cream page, --bg2 panel   beta .ccard sits on --bg2 inside --bg
     doc-top head              beta .doc-top: eyebrow + h1 over a hairline

   The head is beta's .doc-top, the same one /contact/ uses, so the two
   rebuilt routes open identically instead of each inventing a header.
   ============================================================ */

/* ------------------------------------------------------------
   THE ROUTE
   ------------------------------------------------------------
   The parent's `.site-main` carries its own padding-block, which would
   stack on top of the head's own. Zero it and let this section own its
   vertical rhythm, the same way .fab-shop-main does on the archive.

   reading surface, not a gallery: 1100 keeps the line items from running

/* ------------------------------------------------------------
   LAYOUT
   ------------------------------------------------------------
   Items left, summary right. The summary is sticky on wide viewports so
   the Checkout button stays reachable down a long cart.

   STICKY, AND THE GUARD IT NEEDS. instawhew's layout.css:22 sets
   `body { overflow-x: hidden }`. Per CSS Overflow 3 that forces the
   body's computed overflow-y to `auto`, which makes BODY a scroll
   container, and a position:sticky element only sticks against its
   nearest scrolling ancestor. So sticky is dead sitewide unless the
   route opts out. Other routes already do this individually
   (body.home in fab-hero.css, body.single-product in fab-pdp.css);
   this is the same guard for this route, and `clip` is the value
   because it stops horizontal overflow WITHOUT creating a scroll
   container the way `hidden` does. The parent is untouched.
