 - [x] Replace `mb_strlen`/`mb_substr` with `strlen`/`substr` in TfeController, SearchController, Parsedown — mbstring extension not available on production server
 - [x] system.css: retheme to site light palette — remove all `--sys-bg/border/text` dark tokens from variables.css; replace with standard `--bg-*`, `--border-*`, `--text-*` tokens; remap `--sys-syntax-*` to light-appropriate colours; remove dark terminal aesthetic
 - [x] SystemController: PHP-FPM status check — dynamically probe `phpX.Y-fpm` unit derived from running PHP version before static fallback list; add `php8.4-fpm` to cover current production PHP 8.4
+- [x] Favicon: replace SVG placeholder with full PNG/ICO favicon set from `public/assets/favicon/` in `templates/head.php`
