/* ==========================================================================
   Sword Master — stylesheet

   Art direction: bright saturated palette, bold dark outlines, chunky rounded
   UI, playful sans (Fredoka). Every interactive surface has a hard dark border
   and an offset shadow, which is what gives the "sticker" look Poki-style
   games use — and it doubles as a strong focus/contrast affordance.

   Layout is mobile-first: a single column with the battle above the upgrade
   panel. From 900px the two sit side by side.
