- **Styling & Isolation:**
- Mandatory use of scoped CSS (`.razor.css`).
- Strict compliance: Zero inline `<style>` tags are allowed in `.razor` files.
- No global CSS except for design tokens in `app.css`.
- Use `::deep` only when absolutely necessary to style child components.
- **Design System (Nexus Neon):**
- **Color Palette:**
- Primary Accent: `--nexus-neon` (`#00ff99`) - Used for borders, highlights, and icons.
- Neon Glow: `--nexus-neon-glow` / `--nexus-primary-glow` (`rgba(0, 255, 153, 0.3)`).
- Dark Mode: `--nexus-bg` (`#0a0a0a`), `--nexus-card` (`#141414`).
- Light Mode: `--nexus-bg` (`#f8f9fa`), `--nexus-card` (`#ffffff`).
- **No Brand Splitting:** Strict ban on custom purple/indigo/cyan elements or hardcoded accent colors (like `#7c3aed`, `#4c1d95`, `#00b3ff`) on dashboard pages. Neutral/glass surfaces (`rgba(255, 255, 255, 0.05)`) must be used for secondary elements to preserve contrast and ensure the AI/neon-green elements are the focal point.
- **Buttons:**
- Must inherit from the global `.btn-nexus` class in `app.css`.
- Primary Button: `.btn-nexus-primary` (background: `var(--nexus-neon)`, text color: `#000`).
- Secondary Button: `.btn-nexus-secondary` (background: `rgba(255, 255, 255, 0.05)`, border: `1px solid rgba(255, 255, 255, 0.1)`, text color: `#fff`).
- Hover Interaction: `transform: translateY(-2px)`, increased brightness, and a signature primary neon glow shadow.
- **Typography:**
- UI Elements: `Inter` (Sans-Serif) for controls, menus, and labels.
- Reading Content: `Merriweather` (Serif) with `line-height: 1.65` and `letter-spacing: -0.01em` for high readability.

- **Interactive Flow:**
- AI Assistant interactions must be non-blocking and smoothly transition using CSS animations.
- Interactive elements must have clear `:hover`, `:active`, and `:focus` states.
- **Glass Panel Standard:** All primary data panels (`.glass-panel`) must implement the following interaction signature:
- `transition: all 0.3s cubic-bezier(0.4, 0, 0.2, 1)`
- `:hover` state must include: `transform: translateY(-4px)`, increased background opacity, and a subtle `--nexus-neon` border highlight (e.g., `rgba(0, 255, 153, 0.2)`).
- **Glass Panel Standard:** All primary data panels (`.glass-panel`) must implement the following global parameters from `app.css` (only local modifiers like padding and hover offsets should live in scoped CSS):
- Background: `rgba(20, 20, 20, 0.85)` (fallback) / `rgba(255, 255, 255, 0.03)` with `backdrop-filter: blur(10px)` when supported.
- Border: `1px solid rgba(255, 255, 255, 0.05)`.
- Border Radius: `var(--radius-xl)`.
- Transition: `all 0.3s cubic-bezier(0.4, 0, 0.2, 1)`.
- `:hover` state: `transform: translateY(-4px)` (or local offset) and highlight accent `border-color: rgba(0, 255, 153, 0.2)`.
