/* =====================================================================
   Kungfupunk · r4b.css — round 4b (15 Oct 2026, staging): combat, rainblood, gallery, privacy, 404.
   Loaded after style.css and r2.css (and seo.css on combat and rainblood). Adds no new colours: credibility keeps r2's
   jade / ochre / stone; the blue and red of the flashes are the game's own signal colours already in style.css
   (--flash-blue, --red); red otherwise stays on seals and accents. Single column, one visual focus at a time; rhythm comes
   from scale (frames at 852 / 640 / 480 px) and air, never from side-by-side columns. No rounded corners.
   Motion: none that moves layout; one CSS-only scroll reveal of the step numerals (opacity / transform), off under
   reduced motion, static state complete.
