/*
  2026/11/09- "soft" theme, loaded after index.css
  borrowed from Astryx (meta/astryx) themes such as butter / matcha:
   - palette -> semantic token layering, light-dark() pairs
   - radius tiers (inner / element / container / page)
   - layered, tinted shadows (low / med / high)
   - warm cream neutrals + signature accent + a second "fun" color
   - rounded OS typeface (no web fonts), motion tokens, outline buttons
   - categorical colors, bigger touch targets on coarse pointers
