/* ==========================================================================
   METRIC CARDS — static/assets/css/metric-cards.css
   Shared KPI card design for the device transaction pages (pump, well head,
   EFM, generic device_transaction_page). Adapted from pinewave_intelligence's
   metric-cards.css; same class names so the two stay easy to compare.
   Loaded globally from includes/head.html.

   Layout: one line, at most --mc-visible cards (4 on desktop, fewer on
   narrow screens). With that many or fewer, cards stretch evenly to fill the
   row; with more, each keeps exactly one slot's width and the rest sit in a
   carousel — prev/next arrows on desktop (metric-cards.js wraps every
   .mc-row in .mc-carousel and adds them), swipe on touch.

   Values/labels are <div>s on purpose — dark.css recolours every
   `body.dark span/p/h5`, which would override the card's own colours.
