   Layered ON TOP of style.css (loaded after it). Everything
   visual is gated behind html[data-od="full"] / [data-od="low"]
   so switching the FX tier (or prefers-reduced-motion, which
   forces "off") restores the exact classic look with zero
   residue. Colors always come from the shared theme tokens,
   so all 8 themes render this correctly.
