/**
 * VSA Sales Readiness Assessment — presentation layer.
 *
 * Design tokens are inherited from the existing storefront (Space Grotesk +
 * Instrument Serif, the #08101d ground and #2d7ff9 accent) so the diagnostic
 * reads as part of the site rather than a bolted-on quiz.
 *
 * Rules this file holds itself to:
 *   - mobile-first; validated at 320 / 375 / 390 / 430 / tablet / desktop
 *   - no horizontal overflow at any width
 *   - every interactive target at least 44px on its short axis
 *   - visible focus on everything focusable, never removed
 *   - all motion behind prefers-reduced-motion

   That deep end measures 2.91:1, under the 4.5:1 WCAG AA floor for body text.
   Ending the gradient on --accent (#2d7ff9) instead keeps the same two brand
   blues and holds 4.98:1 at the darkest point, 6.96:1 at the lightest.
   Scoped to the assessment so no other page's styling changes. */
