/* Titan Lock (/lock/): its own look, apart from Titan. Warm cream page, rounded type like the app
   (SF Rounded on Apple, Nunito elsewhere), Titan Head as the hero, and the app's five room colours on
   the feature panels (fresh, slipping, dazed, brainrot). Layout patterns: Headspace (solid nav, split
   hero, contained colour panels) and Duolingo (mascot-led hero and download band), via Mobbin.
   Only styles.css's base (consent, language menu, footer skeleton) is shared with the rest of the site. */
