- new src/hooks/ui/useIsMobile.ts (matchMedia + useSyncExternalStore) replacing the resize-handler hook inlined inside pages/site/page.tsx - new src/hooks/ui/usePrefersReducedMotion.ts - new src/data/site/dialogueIds.ts so site and intro components stop carrying hard-coded narrator IDs - siteConfig: add SITE_BACKGROUND_STYLE shared by SiteLayout and SiteMobileBlocker, rename forcedName to presetPlayerName, fix the swapped id/label pairing on situation cards - useSiteStore: rename selectedExperience/Situation to *Index so the stored value (an array index) is obvious in callers - audioConfig: drop dead AUDIO_PATHS placeholders - propagate the renames and SITE_BACKGROUND_STYLE through SiteLayout, SiteWelcomeScreen, SiteSituationScreen and pages/site/page.tsx
