Implementation Report

I have completed the requested features and optimizations for the blog system.

1. Frontend UI Consistency

Visual Style: Aligned the Admin Dashboard with the "Artistic" dark glassmorphism style from UI2.html.
Typography: Applied Playfair Display for headings and Inter for UI text.
Components: Standardized Sidebar, Header, Tables, and Forms with unified glass effects, colors (#d4b383 accents), and spacing.

Runner Engine: Implemented a server/runner package supporting:
- Golang: Compiles and runs main.go.
- PHP: Executes .php scripts.
- Node.js: Executes .js scripts.
- Frontend (HTML/Vue/React): Configured to return code for client-side rendering (safe handling).
Security:
- Implemented context.WithTimeout (default 5s) to prevent infinite loops.
- Uses temporary directories for isolation (basic sandbox).
API: Added POST /api/run endpoint to execute code snippets.

Schema: Updated nl_blog.sql to include roles, permissions, and role_permissions tables.
Middleware: Replaced simple role checks with granular PermissionMiddleware (e.g., users:read, posts:create).
Logic: Implemented full backend logic for:
- Role management (Create/Edit/Delete/Assign Permissions).
- Permission verification on all sensitive routes.
- JWT tokens now carry RoleID for efficient validation.

Unified Theme: Applied the "Glass" style to all Admin pages (Users, Roles, Posts, Works, Dashboard).
High-Frequency Components:
- Tables: Transparent backgrounds, hover effects, status badges.
- Forms: Glass-styled inputs, clear validation states, responsive layout.
Dashboard: Optimized stats cards and activity logs to match the new design.

Database Update: Please execute the updated nl_blog.sql (specifically the new INSERT INTO permissions statements) to populate the new permission data.
Environment: Ensure go, php, and node are installed in your system PATH for the code runner to function properly.
