From 16fa8a3b5de7dd7c4fa763fecbba0063f6b4369b Mon Sep 17 00:00:00 2001
From: Valentin Popov <valentin@popov.link>
Date: Wed, 11 Jun 2025 17:49:14 +0000
Subject: feat: enhance accessibility and language support across components

- Updated various components to include `lang` attributes for improved accessibility and SEO.
- Introduced a new `env.d.ts` file to define environment variables for better type safety.
- Adjusted the print width in `.prettierrc.mjs` for improved code formatting.
- Streamlined the `Header`, `PostElement`, and `SocialLinks` components for better structure and clarity.
- Added language support to blog posts and updated the layout to reflect these changes.
