Replaced CSS background-image in home6 section1 with next/image.

Code Review
This pull request optimizes the hero section by replacing a CSS background image with a Next.js Image component to improve performance and Largest Contentful Paint (LCP). Review feedback suggests removing a redundant inline style that is already defined in the CSS class and improving accessibility by setting an empty alt attribute for the decorative background image.

There was a problem hiding this comment.
The inline style position: "relative" is redundant because the .hero6-section-area class already defines position: relative in the stylesheet (styles/components/hero/_home6.scss, line 5). Removing it keeps the JSX cleaner and avoids duplication of styles.

For decorative background images, it is recommended to use an empty alt attribute (alt="") so that screen readers skip them. Using "Background" provides no useful context to users with visual impairments and can be repetitive for those using assistive technologies.

Replaced CSS background-image in home6 section1 with next/image. Used `priority` to preload the LCP element and `fill` to make it behave as a background, adding `position: relative` to the parent container. Ran `npm run format` to fix Prettier CI check failures.

- Around line 1-17: Prettier formatting errors are causing the CI failure in the
Section1 component; run the formatter (prettier --write) on this file or your
editor's format command to fix whitespace/indentation and JSX formatting for the
Section1 function and its Image usage (the JSX block that renders <Image ...
/>), then re-run CI and commit the formatted file.
- Around line 8-10: The comment in section1.tsx that describes implementation
details of using Next/Image (priority=true, fill, parent div position: relative)
should be removed or replaced with a brief "why" note only; delete the
explanatory "what" comment and either remove it entirely or replace it with a
short rationale (e.g., "Use Next/Image to ensure LCP preload and correct layout
behavior") so the codebase follows the guideline to only document non-obvious
decisions—look for the inline comment near the hero image/parent div and update
it accordingly.

Use decorative alt text for this background image.
On Line 11, this looks presentational. alt="Background" is noise for screen readers; prefer alt="" (optionally aria-hidden="true").

💡 What
Replaced the inline CSS
background-imageincomponents/sections/home6/section1.tsxwith thenext/imagecomponent using thefillandpriorityprops. Addedposition: relativeto the parent container to properly scope the image's absolute positioning.🎯 Why
The hero image is typically the Largest Contentful Paint (LCP) element on the page. Loading it via CSS
background-imageprevents Next.js from automatically optimizing the image and the browser from discovering it early. Usingnext/imagewithpriorityinjects a<link rel="preload">tag in the document head, allowing the browser to fetch the image sooner, which directly improves LCP times.📊 Impact
Expected to significantly improve the LCP metric for the "home6" layout by prioritizing the fetch of the hero image and serving optimized formats (like WebP/AVIF depending on configuration), instead of relying on CSS parsing to trigger the download.
🔬 Measurement
Verify the improvement by running Lighthouse on the
/home6route (or any route using this section) and comparing the LCP time before and after the change. Observe the network tab to confirm the image is preloaded early in the document lifecycle.PR created automatically by Jules for task 4325450604449609944 started by @anyulled
