/* Every scrollable table wrapper (was plain "overflow-x:auto" - horizontal-scroll-only on
   mobile) also gets a bounded height + vertical scroll here, specifically so its own header
   row can use position:sticky. CSS forces overflow-y to "auto" the moment overflow-x isn't
   "visible" (there's no such thing as x-scroll/y-visible on the same box), which already
   silently made every sticky header below inert - a "position:sticky" element only sticks
   within its NEAREST ancestor that establishes a scroll container, and that was already this
   div, not the page; it just had no visible effect because the div's own height (unbounded)
   meant it never actually scrolled internally. Giving it a real max-height turns that
   pre-existing scroll container into one that's actually usable, so the header now stays
   pinned to the top of the table as its rows scroll underneath - same fix needed regardless
   of whether "always visible" was implemented as page-scroll or a bounded pane; a bounded
   pane is the only version that's reliably correct across browsers when a table also needs
   to scroll horizontally on narrow screens. */

/* Transakcie table: fits the viewport width on desktop (no side-scrolling) by switching to
   a fixed layout instead of letting long Protistrana/Detail text force the table wider than
   its container. Short/predictable columns (date, direction, amount, VS, the pair/unpair
   action) get `nowrap` and enough room to never wrap - only the free-text columns
   (Protistrana, Detail, Stav) wrap, and only at word boundaries (no word-break:break-word,
   which was breaking even short words like "Smer" or "Spárovať" letter-by-letter when a
   column was too narrow for them). Phones AND tablets (below a typical desktop breakpoint)
   fall back to the normal auto-layout table inside its scrollable wrapper, since columns
   this narrow would otherwise squeeze every cell down to a sliver. */
