/* ==========================================================================
   Magic in the Mind — site styles
   Strict black / white / grayscale palette, no accent colour. (The only real
   colours on the site live inside the Stroop game board, in brain-lab.css.)
   Icons are inline SVG from Lucide (lucide.dev, ISC licence), sized and coloured here.
   Contrast notes (WCAG 2.x):
     #ffffff on #161616  18.1:1      #ffffff on #0a0a0a  19.8:1
     #d0d0d0 on #161616  12.0:1      (body copy on dark, ~ white at 82%)
     #0a0a0a on #ffffff  19.8:1      #4a4a4a on #ffffff   8.9:1
   Colour roles are custom properties so every component inverts
   cleanly between dark bands (default) and light bands.

   Motion rules: only transform and opacity are ever animated, durations stay
   between 150 and 600 ms, and prefers-reduced-motion collapses everything to
   its final, static state (see the end of this file).
