 All new UI components and pages must be built with accessibility in mind from the start. Agents must prioritize the following core principles:
 
 ### 1. Semantic HTML & Structure
+
 - **Use HTML5 elements:** Prioritize `<header>`, `<nav>`, `<main>`, `<section>`, `<article>`, and `<footer>` over generic `<div>`s. Screen readers depend on this semantics.
 - **Heading hierarchy:** Always use headings in logical order (`<h1>` → `<h2>` → `<h3>`) without skipping levels.
 - **Actions vs Navigation:** Use `<button>` for actions and `<a>` solely for links/navigation. Avoid using `<div>` or `<span>` with `onClick` handlers.
 
 ### 2. Text Alternatives (Images & Icons)
+
 - **Image `alt` tags:** All `<img>` elements must have meaningful `alt` text. Describe the image's function or content (e.g., `alt="Persona usando la app en un celular"` not `alt="imagen1"`). If an image is purely decorative, strictly use `alt=""`.
 - **SVGs and ARIA:** Ensure decorative SVGs have `aria-hidden="true"`. Interactive SVGs must have an `aria-label` or `<title>`. Provide `aria-` attributes (`aria-expanded`, `aria-describedby`) for dynamic elements where visual context isn't enough.
 
 ### 3. Color and Contrast
+
 - **Contrast Ratios:** Ensure all text has sufficient contrast against its background. Avoid light grey text on white backgrounds.
-- **Do not rely on color alone:** Always provide an additional visual indicator alongside color (e.g., rather than saying "Fields in red are required", say "Fields marked with * are required").
+- **Do not rely on color alone:** Always provide an additional visual indicator alongside color (e.g., rather than saying "Fields in red are required", say "Fields marked with \* are required").
 
 ### 4. Keyboard Navigation
+
 - **Tab navigation:** All interactive elements must be fully functional using only the keyboard (`Tab` and `Enter`/`Space`).
 - **Visible Focus:** Ensure a clear, visible focus state for all focusable elements. Never use `outline: none;` without providing a custom visible focus ring (e.g., using Tailwind's `focus-visible:ring`).
 
+### 5. External Links & New Tab Notifications
+
+- **New tab links:** All links with `target="_blank"` must include `aria-label` that informs users the link opens in a new tab.
+- **Use centralized translations:** Use `menuTexts[lang].new_tab` for consistent translations across all languages:
+  - Spanish: `(se abre en nueva pestaña)`
+  - English: `(opens in new tab)`
+  - Catalan: `(s'obre en una pestanya nova)`
+- **Implementation example:**
+  ```astro
+  <a
+    href="https://example.com"
+    target="_blank"
+    rel="noopener noreferrer"
+    aria-label={`${linkText} ${menuTexts[lang].new_tab}`}
+  >
+    {linkText}
+  </a>
+  ```
+- **Required imports:** Always import `menuTexts` when adding external links:
+  ```astro
+  import {menuTexts} from '@/i18n/menu' const menuT = menuTexts[lang as keyof typeof menuTexts]
+  ```
+
 ### Agent Enforcement
+
 - When generating or modifying components, agents **must** proactively apply these accessibility standards without needing explicit prompting from the user.

 ### Layout and Metadata
+
 - Every page **must** use the `Layout` component from `src/layouts/Layout.astro`.
 - Pass a unique and descriptive `title` and `description` (150-160 characters) to the `Layout` component.
 - The `Layout` component automatically handles canonical URLs, social media tags (OG/Twitter), and `hreflang` tags.
 
 ### Semantic HTML and Accessibility
+
 - **H1 Tags**: Use exactly one `<h1>` per page.
 - **Headings**: Maintain a logical hierarchy (`h2`, `h3`, etc.).
 - **Images**: All `<img>` tags must include a descriptive `alt` attribute.
 - **Links**: Use descriptive text for links. Avoid generic phrases like "click here".
 
 ### Analytics and Monitoring
+
 - Use the `PUBLIC_GA_ID` environment variable for Google Analytics.
 - Do not hardcode tracking IDs.
