A dark, glassmorphism console with vibrant neon accents.\r\n        Advanced Features:\r\n        1. Intuitive Binomial Input: Users interact with a clear (ax+b)(cx+d) structure.\r\n        2. FOIL Synthesis Grid: A live 2x2 grid that visually breaks down each step of the FOIL expansion.\r\n        3. Live Combination Panel: Clearly shows the Outer and Inner terms being combined into the linear term.\r\n        4. Holographic Result: The final equation animates in with a satisfying holographic glow.\r\n        WP-Safe: Uses a unique \"fts-\" prefix on all elements and high-specificity CSS for a 100% conflict-proof guarantee.\r\n    -->\r\n    <style>\r\n        \/* CSS VARIABLES *\/\r\n        .fts-container {\r\n            --fts-bg: #11131C;\r\n            --fts-accent-magenta: #FF00A5;\r\n            --fts-accent-cyan: #00E0FF;\r\n            --fts-text-primary: #F0F2F5;\r\n            --fts-text-secondary: #9DA3B4;\r\n            --fts-panel-bg: rgba(34, 38, 49, 0.6);\r\n            --fts-border: rgba(72, 82, 115, 0.4);\r\n            --fts-shadow: rgba(0, 0, 0, 0.3);\r\n            --fts-font-primary: system-ui, -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, Helvetica, Arial, sans-serif;\r\n            --fts-font-mono: \"SF Mono\", \"Menlo\", \"Consolas\", \"Courier New\", monospace;\r\n            --fts-radius: 16px;\r\n        }\r\n\r\n        \/* --- BULLETPROOF BASE & HERO LAYOUT --- *\/\r\n        .fts-container {\r\n            font-family: var(--fts-font-primary);
