The entire skate-spots codebase was accidentally copied into src/src/ and public/public/ instead of src/ and public/ directly. This left the real src/ directory as blank MKStack template stubs, explaining why the landing page showed the default template instead of SkateSpots. Changes made: - Copied all files from src/src/ up to src/ (App.tsx, AppRouter.tsx, main.tsx, all pages, components, hooks, contexts, lib, i18n, test) - Copied all files from public/public/ up to public/ (images, manifest, etc.) - Deleted src/src/ and public/public/ nested directories - Removed HelloWorld.tsx template stub from pages/ - Retained the previously fixed index.css (Tailwind v3 directives) Full skate-spots feature set is now active: - All 30+ routes (map, events, spots, coaches, marketplace, wallet, etc.) - NWCProvider, LanguageProvider, PWAInstallPrompt, AmberCallbackHandler - Skate community relays (goskatespots.nostr1.com, wotr.relatr.xyz, etc.) - Outfit Variable font, Amber pre-check in main.tsx - All hooks (useSkateSpots, useCoaches, useZaps, etc.) - i18n support (en/es) Co-authored-by: shakespeare.diy <assistant@shakespeare.diy>
