/* PrepGap — light glassmorphic theme.

   Self-hosted only: fonts live in assets/fonts, so the CSP stays at 'self' and
   nothing appears in a visitor's network tab but our own domain.

   Type scale is deliberately larger than a typical marketing page: the audience
   reads this on a phone, at night, quickly. 16px body / 15px card copy is the
   floor, never below.

   Motion uses transform + opacity only, and every transition is disabled under
   prefers-reduced-motion. */

   The CSP is `style-src 'self'` with no 'unsafe-inline', so a style="" attribute
   is refused by the browser. Anything that would have been an inline style must
   be a class. Discrete progress widths rather than a computed one, because the
   quiz has a fixed number of steps. */
