/* Ship Responsibly · v2 design tokens + layout
   Production extraction of v2/playful-landing.html with fixes:
   - --ink-dim darkened to pass AA on white (3.0:1 -> 5.0:1)
   - --pink-hot reserved for backgrounds/badges; never used as text on white
   - @supports fallback when -webkit-text-stroke is unsupported
   - :focus-visible ring works on light + dark surfaces
   - prefers-reduced-motion neutralises every transition/transform
   - .book .b-foot .pn override so dim text on the lavender cover stays readable
