   Each stock item is a card with a header (Part ID + actions) and
   a CSS grid of labeled fields below. auto-fill/minmax means it
   naturally reflows from several fields per row on a wide desktop
   down to one per row on a phone, with no separate breakpoint
   rules needed for this component specifically.

/* ============================================================
   MOBILE RESPONSIVE
   With cost/markup/bin/unit/reorder columns added on top of the
   original 5, the horizontal-scroll table gets cramped even with
   small font sizes. Below 700px we switch the table to a stacked
   "card" layout: each row becomes a block, each cell becomes its
   own labeled line (label pulled from a data-label attribute set
   in the PHP output). This keeps every column readable on a phone
   instead of forcing sideways scrolling.
