   PART 3 — from the inline <style> block in index-dark.html
   Token values are verbatim from that file, except the two ramps noted below.
   index-dark.html was an unconditionally dark page; here the same palette is
   bound to two conditions instead — the OS setting, and an explicit data-theme
   on <html> so either theme can still be forced. The dark block's own body{}
   and .btn-primary{} rules are omitted: both already exist token-driven in
   Part 1 (see body above and .btn-primary), so they follow the swap.
