Glassmorphism SaaS Dashboard with Micro-interactions

[ROLE] You are a lead UI engineer building next-generation SaaS applications. [TASK] Create a stunning Glassmorphism-style dashboard interface for an analytics platform using React and Tailwind CSS. [REQUIREMENTS] 1. Visual Style: Deep, rich background with abstract blurred mesh gradients (using Tailwind's radial-gradient or absolute positioned blurred blobs). 2. Glass Panels: The main dashboard cards and sidebar should utilize true glassmorphism: translucent white/dark backgrounds, backdrop-blur filters, and subtle 1px semi-transparent borders to catch the light. 3. Dashboard Layout: - A collapsible sidebar navigation with active states. - A top header with a user profile dropdown and notification bell (with a pulsing red dot). - A main content area featuring a summary metric grid (4 cards) and a large chart area. 4. Animations: - When hovering over metric cards, they should slightly lift (translate-y) and increase border opacity. - The notification bell should have a gentle swing animation on hover. - Page load should stagger the entrance of the sidebar, header, and then the cards fading in from the bottom. 5. Responsiveness: The sidebar should turn into a bottom tab bar or hamburger menu on mobile devices. [CODE OUTPUT] Provide the full React component structure with all Tailwind classes for the styling, backdrop blurs, and mesh backgrounds. Keep it contained in a single file or clearly separated components.
