/* BriskFyr site sheet — v2. Covers index_v4.html / index_v4_light.html (hero:
   two-column top, centered CTA, full-width GUI animation) AND pricing.html
   (centered top bar + gradient hero + pricing cards + FAQ). Reuses the app's
   design tokens (identical values to style_opt.css). All surfaces are token-
   driven, so `body.theme-light` themes the pricing page too. Vanilla CSS. */
