🧱 Architecture

The platform follows Next.js App Router conventions and a modular structure:

/app                    # App Router (layout, page, error, loading, not-found)
  /tools/               # layout.tsx (ToolNavbar + main + ToolFooter)
  /tools/[slug]         # One route per tool; page.tsx + _components/ (colocated, private)
/components             # Shared UI (import from direct files)
  /layout               # Header.tsx, Footer.tsx
  /shared               # TextArea.tsx, CopyButton.tsx, ToolCard.tsx, CodeBlock.tsx
  /tool                 # ToolNavbar.tsx, ToolFooter.tsx, ToolPageHeader.tsx
/lib                    # Business logic (import from direct files)
  /formatters/json.ts   # JSON formatter
  /encoders/base64.ts   # Base64 encoder/decoder
  /parsers/jwt.ts       # JWT parser
  tools.ts              # Tool list, getToolBySlug(), getToolMetadata()

• Colocation: Tool-specific client components live in app/tools/<slug>/_components/ (underscore = private, not a route).
• Imports: Use direct file paths (e.g. @/components/tool/ToolNavbar, @/lib/formatters/json). No index/barrel files.
• Tool pages: Each tool page uses getToolBySlug(slug) and getToolMetadata(slug) from @/lib/tools and calls notFound() when missing.

Each tool runs as an isolated client-side module.
