/* ==========================================================================
   Poké Arena — handheld-era design system

   Spacing  4 / 8 / 12 / 16 / 24 / 32 / 48 / 64 / 96 (4-point scale, no exceptions)
   Type     Heading: Press Start 2P, sizes on its 8px grid — 16/24 · 24/32 · 32/48 · 48/64
            Body:    Pixelify Sans — 14/20 · 16/24 · 18/28
   Shape    Square corners everywhere. 2px ink borders. Hard, un-blurred drop
            shadows: 4px for containers, 2px for controls.
   Color    Paper + ink, with the series primaries: red (brand, P1), blue (P2,
            focus), green (HP, success), yellow (HP mid, round wins).
   Motion   Stepped timing (steps()) so movement reads like sprite frames.
