   BIDSvue demos — design system
   Ported from BIDSvue's own theme tokens (src/lib/styles/theme.css): the
   same surfaces, borders, text ramp, and the six accent schemes (Orange is
   the release default; Sage, Garnet, Periwinkle, Violet, Indigo optional).
   Light + dark, with the accent bleeding into focus rings, links, chips,
   and the translucent glow around every screenshot.
