/* === PORTRAIT HUD REFLOW =================================================
   At 390×844 portrait the HUD overlapped the dual-stick safe zone and the
   gear button. We:
     • Pull #hud padding tight to the top, respecting safe-area insets
     • Shrink the HUD blocks so score / wave / aether / level all fit on
       a 390px row with the gear button visible
     • Hide combo-display in portrait (it's centered top-vertical on desktop
       and visually clashes with the cramped portrait HUD)
     • Float the mobile controls above the iOS home indicator
