Code Review
This pull request optimizes background images by replacing CSS background-image with the Next.js <Image> component, which is a great performance improvement. My review includes suggestions to ensure the correct positioning of these new images and to improve accessibility by using appropriate alt attributes for decorative images. I've also updated the related test to accommodate these changes.

In `@components/layout/footer/Footer8.tsx`:
- Line 1: Run Prettier on components/layout/footer/Footer8.tsx to fix the
formatting warning: ensure the "use client" directive is correctly placed as the
first line and the file is formatted (trailing newline, proper indentation and
semicolons/quotes per project Prettier config). You can either run `prettier
--write components/layout/footer/Footer8.tsx` or apply your editor's format
command so the file passes CI formatting checks.
🧹 Nitpick comments (2)
__tests__/components/Footer8.test.tsx (2)
9-21: Test coverage is minimal — consider expanding for broader Footer8 validation.This single test verifies the background image optimization, which aligns with the PR goal. However, Footer8 has non-trivial logic (year extraction from pathname, dynamic links). Consider adding tests for edge cases like a pathname without a year (e.g.,
"/about-us"→ default"2026") to get more value from this test file.
18-20: Consider explicitly mockingnext/imagefor consistency with other tests in the suite.The test currently relies on
nextJest()fromnext/jest(configured injest.config.js) to automatically handle thenext/imagecomponent, which allows thetoContain("header-bg21.png")assertion to work. However, this approach is inconsistent with other test files like__tests__/pages/speaker-detail.test.tsxand__tests__/pages/job-offers.test.tsx, which explicitly mocknext/image. For clarity and maintainability, consider either:
- Adding an explicit
next/imagemock to this test file (consistent with other tests)- Documenting in code that the test relies on
nextJest's automatic handling- If concerned about robustness, consider using
decodeURIComponent()on the src (as done inBackgroundCarousel.test.tsx)

💡 What: Replaced CSS 'background-image' in 'style' props with Next.js![]()
component in 'Footer8' and 'Section2'.![]()
enables lazy loading, format optimization (WebP/AVIF), and proper sizing.
🎯 Why: CSS background images are not optimized by Next.js, leading to larger file sizes and slower LCP. Using
📊 Impact: Reduces initial page load weight by optimizing large hero/footer background images.
🔬 Measurement: Verified visually using Playwright and with unit tests.
