   YOUTH STUDY BIBLE SKIN (mockup c2 "Marginalia Pop").
   Every rule is scoped under `.youth` (class on <html>, set before first paint).
   Without that class nothing here applies, so the classic C0 look is untouched.
   Highlighter colors are the brand: flat color blocks, 3px outlines, offset shadows.
