/* Drink grid: 3 equal columns. Rows no longer assume a fixed count (the old
   "exactly 5 rows fill the area" formula squeezed every row into 1/5 of the
   height regardless of how many rows actually existed — 4 rows of drinks
   looked cramped, with a wasted empty row's worth of space below them).
   `minmax(min-content, 1fr)`: the floor is each row's own natural content
   height (name + price + Pfand at whatever font-size is active — this
   already tracks the smaller mobile font sizes below with no separate
   number needed) rather than a guessed pixel value, and 1fr means rows are
   equal height and stretch to fill any leftover space when there's room —
   but never shrink below that content-derived floor. When there are enough
   rows that even their natural height doesn't fit the visible area, the
   grid holds every row at that floor and the whole thing scrolls
   (overflow-y: auto) instead of cramming rows smaller — "otherwise go for
   what fits". */

/* #39 follow-up: overflow-y: auto directly on a flex column that also has
   justify-content: flex-end doesn't reliably scroll in WebKit/Safari (the
   iOS 12+ targets this app builds for) — the flex-end-justified overflow
   gets clipped instead of becoming a scrollable region, so from the user's
   side it looked identical to the original overflow: hidden bug. Standard
   workaround: the overflow/scroll and the flex-end alignment can't live on
   the same element — .cart-items is now a plain scroll container (no
   justify-content), and .cart-items-inner is the flex column that actually
   bottom-anchors short lists via min-height: 100% (a floor, not a fixed
   height, so it still grows past 100% and scrolls normally once content
