         vertical chip stack. Cards become 60px wide emoji+cost chips.

   TODO: Card breakout from game frame is by-design (position:fixed,
         z:2100) but on portrait mobile the fan should be anchored
         to env(safe-area-inset-bottom) and use max-height: 30vh
         to avoid occluding game grid entirely.

   TODO: Add CSS transition on .hand-fan-container position/transform
         so orientation changes produce smooth card reflow (~200ms)
         instead of instant pop.

   TODO: Investigate using CSS anchor-positioning (when supported)
         to tether fan container to #str-combat-window during combat
         mode, so it moves with the STR window on landscape panels.
