/* ============================================================
   V9 cart-in-dock. The cart's legacy DOM (cart-items / cart-footer / rows /
   method picker / splits) renders inside the workspace dock now — this bridge
   re-skins it to obsidian and re-lays it for the dock width. On phone the dock
   is already full-screen, so the cart gets the whole screen (fixes the old
   cramped drawer). Scoped under .v9-cart-panel; dies with the legacy cart CSS
   in Stage C.
   ============================================================ */

/* Single-scroll: the dock body scrolls the whole cart. The panel min-fills the
   body so items flex-grow to push the footer to the bottom when the cart is
   short; when it's long, the body scrolls (the cart's own footer can exceed a
   phone viewport, so a pinned footer would starve the items). */
