   ROZCESTNÍK (branch hub) — index.html only.
   One viewport, no scroll, on any device: html/body are locked to
   100% height with overflow hidden, and every size below is a clamp()
   tuned to still fit a short mobile viewport (~570px tall) with the
   logo showing. If a 3rd/4th branch card ever makes the grid taller
   than that, drop --hub-logo-h below to claw back space before
   touching anything else.
