   TOKEN CONTRACT (CAP-ID: OPS-CC-THEME-001)
   Every paintable surface MUST reference a token below — never a literal hex
   or rgba dark value. If a surface hardcodes a color it will not flip in light
   mode. That was the root cause of the "light chrome / dark cards" bug.

   Surface ladder (low -> high elevation):
     --bg          page canvas
     --surface-1   cards, sections, panels (was a hardcoded dark rgba)
     --surface-2   nested rows, chips, inputs, tabs
     --surface-3   table headers, sticky heads, footers
     --surface-sunken  wells / progress tracks / param tables
     --scrim-*     translucent chrome (header/nav/context/popover)
