/* =========================================================================
   강해지는 프롬프트! (Tsuyokunaru)
   Design system - tinted glassmorphism.

   Built from the emerald glass card recipe: a low-alpha tinted fill,
   blur(20px) saturate(160%), a mint hairline border, a deep coloured drop
   shadow and one soft inset white glow. No displacement filter.

   Pill controls and the inset-track / raised-thumb treatment on toggles
   come from the neumorphic reference, rendered in the glass idiom.

   Shape rule (locked):
     panels / sheets  -> --r-lg (18px)
     cards / rows     -> --r-md (12px)
     inputs           -> --r-sm (10px)
     buttons, toggles -> --r-pill (9999px)

   Accent rule (locked): one family only, the emerald / mint ramp.
   The crimson logo is the single warm element, and that is deliberate.
