Philosophy
Minimal PHP for modern conveniences. Prioritize longevity (decade-scale maintainability) by avoiding volatile dependencies. Strictly add only what's essential—readable, simple, and future-proof.
Core Constraints
Minimalism: Only essential tech (HTML, PHP 8.4+, CSS). No JS, frameworks, build tools, or package managers. Comments only for major sections.
Frontend:
- Classless, semantic HTML5
- Modern CSS: nesting,
oklch(), grid,clamp(), logical props - Responsive via fluid typography + flexible layouts
Security:
- Path validation blocks traversal
- Files restricted to document root
- Strict MIME types + no direct user-input execution
Code Style
PHP: Modern syntax (arrow functions, null coalescing, match). Type hints where practical. Ternary for simple conditionals. Single-purpose functions.
CSS: Variables, native nesting, grid layouts. clamp() over @media. Relative units > pixels.
Templates: Escape output (htmlspecialchars() for UGC). Short echo tags (<?= $var ?>).
