   Laser Cats vs Zombies - page, HUD and touch control styling.
   The 3D game is rendered by Three.js onto the <canvas>; this
   file styles the page frame, the HUD overlay, the on-screen
   joystick, the weapon bar and the menu screens.

   Mobile-first, tuned for iPad landscape. Touch controls scale
   with viewport units and respect safe-area insets.
