/* =========================================================================
   PDF to JPG — design tokens
   Bold/modern palette with one strong electric-indigo accent, distinct
   from success (green) and error (red) so states never get confused.
   Light:
     --ink #0B0E14  --ink-soft #545B66  --paper #FFFFFF  --panel #FFFFFF
     --brand #3D5AFE  --brand-dark #2A3FCC  --brand-tint #EAECFF
   Dark (opt-in via the header toggle, not the default):
     --paper #0A0C11  --panel #12151D  --ink #F4F6FA  --brand #7C90FF
   Type: system font stack (fast, no webfont request); a bigger, tighter
   type scale carries the "bold & modern" direction instead of a second
   display face.
