## SUMMARY

PLUTONIUM IS A FREE, OPEN-SOURCE NEXT.JS 11 + TAILWINDCSS 2 MARKETING/STARTUP LANDING-PAGE TEMPLATE BY SAURISH SRIVASTAVA (GITHUB: MINOR). IT SHIPS A SINGLE-PAGE MARKETING SITE (HERO, SPONSORS, FEATURES, PRICING, FOOTER) PLUS A DELIBERATE, PLAYFUL "DEMO" PAGE THAT REUSES NEXT.JS'S 404 ROUTE AS AN EASTER EGG (THE NAV'S "DEMO" LINK AND THE HERO'S "SEE A DEMO" BUTTON BOTH POINT AT `/404`). THE TEMPLATE ADVERTISES BUILT-IN DARK-MODE SUPPORT VIA `next-themes` (CLASS-BASED, SYSTEM-PREFERENCE AWARE, NO FLASH), TAILWIND JIT MODE, AND `next-seo` INTEGRATION. THIS CLONE REPRODUCES BOTH PAGES, THE STICKY BLURRED-GLASS NAV WITH MOBILE HAMBURGER MENU, THE DARK-MODE TOGGLE (PERSISTED, SYSTEM-AWARE, NO-FLASH BOOT SCRIPT), AND ALL HOVER/TRANSITION EFFECTS (IMAGE SCALE-UP ON HOVER, BUTTON COLOR TRANSITIONS, GRAYSCALE-TO-COLOR SPONSOR LOGOS, LINK COLOR FADES).
