Enhance security and localization features across the application

- Added rehype-sanitize plugin to the markdown configuration for improved security against XSS attacks. - Updated environment variables in the codebase to include new configurations for SMTP and monitoring. - Implemented secure headers in server and Nginx configurations to bolster security. - Refactored email handling to prevent spoofing by ensuring safe sender addresses. - Improved localization by updating language persistence and button components for better user experience. - Enhanced the uptime API and contact form with better error handling and logging practices. - Updated dependencies in package.json and package-lock.json for better performance and security.

+## Quick wins (top 5)
+
+1) Add `rehype-sanitize` (already applied) and remove unnecessary `set:html` usages to prevent XSS and improve content robustness.
+2) Eliminate CDN for Mermaid; use local dependency (already applied) to improve performance, privacy, and CSP compliance.
+3) Optimize hero and large images using `src/components/common/Image.astro` everywhere; enforce `width`/`height` and lazy loading for non-LCP images.
+4) Reduce JS on static pages by avoiding unnecessary client-side logs and inline scripts; prefer islands.
+5) Improve form UX: ensure visible error messages, labels, and aria-live regions are consistent; keep focus management for spam/manual-review flows.
+
+## Issues table
+
+| ID | Page/Component | Problem | Impact | Fix |
+|---|---|---|---|---|
+| D1 | `Hero/Hero2/HeroText` | `set:html` in multiple slots | Med | Potential rendering inconsistencies and sanitization risk | Prefer rendering plain strings or sanitized HTML only |
+| D2 | `Image.astro` usage | Not consistently used across pages | High | LCP/CLS and bandwidth | Replace `<img>` with `Image.astro` wrapper for optimization |
+| D3 | `Footer.astro` | email obfuscation used `innerHTML` | Low | Minor XSS risk | Switched to `textContent` (applied) |
+| D4 | Typography | Some lines exceed 85ch | Low | Readability | Use `max-w-prose` or `ch`-based widths in content wrappers |
+| D5 | Forms | Inline scripts manage state | Med | Maintainability/perf | Extract to small islands if complexity grows |
+
+## Before/After snippets
+
+Replace `set:html` for simple line breaks:
+
+```astro
+<!-- Before -->
+<div set:html={text.replace(/\n/g, '<br/>')}></div>
+
+<!-- After -->
+<div>
+  {text.split('\n').map((line) => (<>
+    {line}<br/>
+  </>))}
+  </div>
+```
+
+Avoid `innerHTML` when setting modal titles:
+
+```js
+// Before
+titleEl.innerHTML = title;
+
+// After
+titleEl.textContent = String(title);
+```
+
+## Asset and typography guidance
+
+- Use `src/components/common/Image.astro` for all images. Ensure: `alt` always set, `loading="lazy"` for non-LCP, explicit `width/height` to prevent CLS.
+- Fonts: prefer `font-display: swap` (already via Inter variable). Limit weights/axes for performance.
+- Containers: keep readable line length using `max-w-prose` or `max-w-[75ch]` for long text sections.
+- Hydration: ensure islands only where needed (forms, uptime widgets). Keep content pages server-rendered.

+## Executive summary
+
+Astro SSR is enabled; endpoints handle contact, uptime, and commits. Main risks were HTML injection and missing headers. Minimal edits applied: enable `rehype-sanitize`, drop Mermaid CDN, avoid `innerHTML` where not needed, reduce PII in logs, soften Gemini init, and add headers/CSP snippets for both static hosts and Nginx.
+
+## Risk table
+
+| ID | File/Path | Issue | Severity | Why it matters | Fix |
+|---|---|---|---|---|---|
+| S1 | `astro.config.ts` | MD/MDX not sanitized | High | XSS via content/slots | Add `rehype-sanitize` |
+| S2 | `src/pages/[lang]/topdesk.astro` | CDN Mermaid + `innerHTML` | High | CSP bypass/XSS | Use local `mermaid`, keep injection controlled |
+| S3 | `src/components/widgets/ModernEducation.astro` | Title via `innerHTML` | Med | XSS if title contains HTML | Use `textContent` |
+| S4 | `src/pages/[lang]/index.astro` | `set:html` for line breaks | Low | Avoidable HTML injection | Render lines with `<br/>` |
+| S5 | `src/pages/api/contact.ts` | PII in logs | Med | Privacy/legal | Remove PII logs |
+| S6 | `src/utils/gemini-spam-check.ts` | Throws when key missing | Med | Startup failure | Lazy init, fail open |
+| S7 | `public/_headers`, `nginx/nginx.conf` | Missing headers/CSP | High | XSS/MIME sniffing | Add strict headers and CSP |
+| S8 | `src/middleware.ts` | 301 for lang redirect | Low | Sticky cache | Use 302 |
+| S9 | `src/pages/api/uptime.ts` | Verbose error detail | Low | Info leakage | Return generic details |
+
+## Detailed findings with references
+
+- S1: `astro.config.ts` now includes `rehype-sanitize` alongside existing plugins.
+- S2: `src/pages/[lang]/topdesk.astro` imports `mermaid` locally and renders SVG without remote CDN.
+- S3/S4: Components/pages adjusted to avoid `innerHTML`/`set:html` for simple cases.
+- S5/S6/S9: API/util logs are minimal; no PII or stack traces in prod responses.
+- S7: Headers added for both Nginx and static hosting.
+- S8: Middleware redirect switched to 302.
+
+## Applied patches (concise)
+
+1) Enable sanitize in Astro markdown
+
+```diff
+--- a/astro.config.ts
+++ b/astro.config.ts
+@@
+   markdown: {
+     remarkPlugins: [readingTimeRemarkPlugin],
+-    rehypePlugins: [responsiveTablesRehypePlugin, lazyImagesRehypePlugin],
+    rehypePlugins: [rehypeSanitize, responsiveTablesRehypePlugin, lazyImagesRehypePlugin],
+   },
+```
+
+2) Remove CDN and render Mermaid locally
+
+```diff
+--- a/src/pages/[lang]/topdesk.astro
+++ b/src/pages/[lang]/topdesk.astro
+@@
+-      const mermaid = await import('https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs');
+      const mermaidModule = await import('mermaid');
+      const mermaid = mermaidModule.default || mermaidModule;
+@@
+-          const { svg } = await mermaid.default.render(id, mermaidCode);
+          const { svg } = await mermaid.render(id, mermaidCode);
+```
+
+3) Avoid `innerHTML` for titles; use `textContent`
+
+```diff
+--- a/src/components/widgets/ModernEducation.astro
+++ b/src/components/widgets/ModernEducation.astro
+@@
+-      const tempDiv = document.createElement('div');
+-      tempDiv.innerHTML = title;

+      const titleEl = document.getElementById('educationModalTitle');
+      if (titleEl) titleEl.textContent = cleanTitle;
+```
+
+4) Replace trivial `set:html`
+
+```diff
+--- a/src/pages/[lang]/index.astro
+++ b/src/pages/[lang]/index.astro
+@@
+-          <div class="text-lg pt-4 method-highlights" set:html={explosive.approach.highlights.replace(/\n/g, '<br/>')}>

+          <div class="text-lg pt-4 method-highlights">
+            {explosive.approach.highlights.split('\n').map((line) => (
+              <>
+                {line}
+                <br />
+              </>
+            ))}
+          </div>
+```
+
+5) Reduce PII logging; lazy Gemini init
+
+```diff
+--- a/src/pages/api/contact.ts
+++ b/src/pages/api/contact.ts
+@@
+-    console.log('Client IP:', ipAddress);
+    // avoid logging IP in production
+@@
+-      console.log('Rate limit exceeded');
+      console.warn('Rate limit exceeded for contact endpoint');
+```
+
+```diff
+--- a/src/utils/gemini-spam-check.ts
+++ b/src/utils/gemini-spam-check.ts

+const GEMINI_API_KEY = process.env.GEMINI_API_KEY;
+const genAI = GEMINI_API_KEY ? new GoogleGenerativeAI(GEMINI_API_KEY) : null;
+```
+
+6) Headers/CSP
+
+- Static host `_headers` additions in `public/_headers` (applied).
+- Nginx secure headers added in `nginx/nginx.conf` (applied).
+
+Starter CSP (static host file already contains a commented safer baseline):
+
+```text
+Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https://cdn.pixabay.com https://raw.githubusercontent.com; font-src 'self' data:; connect-src 'self'; frame-ancestors 'none'; base-uri 'self'; form-action 'self'
+```
+
+If you keep inline scripts, use Astro nonces or move to external files to avoid `'unsafe-inline'` for scripts entirely.
+
+## Follow-up tasks
+
+- Add CI with: `npm ci`, `npm run check`, `npm run build`, `npm audit --omit=dev`.
+- Consider switching `output: 'server'` to prerender where feasible for brochure pages; keep APIs SSR.
+- Review all remaining `set:html` occurrences and ensure content sources are trusted/sanitized.
+- Document `.env` variables; `.env` example added to README.
