/* Created: 2026-10-20 (AUD-2293); identity pass 2026-10-20 (AUD-2296)
   Purpose: styles for the listening quiz at demo.intrect.io/survey/ (quiz, method and privacy pages).
   World: the intrect.io home (web/landing/css/redesign.css, `.rd` tokens) - studio black ground,
   graphite panels, one action blue, hairlines, flat. The quiz is a listening rack: the only lit
   thing on screen is the clip that is playing.
   Fonts are self-hosted under /fonts (CSP font-src 'self'); the files are OFL, notices alongside.
   CSP style-src 'self': nothing here relies on inline style attributes. */
