+      <p className={styles.cardDesc}>{description}</p>
+      <div className={styles.cardArrow}>→</div>


The emoji in cardIcon is decorative, but as plain text it will be announced by screen readers (often as “rocket”, “hammer and wrench”, etc.) before the card title. Consider marking the icon as decorative (e.g. aria-hidden) or switching to role="img" with an explicit accessible name if the emoji conveys meaning beyond the title.

These new SVG requires are only referenced by HomepageFeatures, but HomepageFeatures itself doesn’t appear to be imported anywhere under website/src anymore. If the redesign removed this section from the site, consider deleting the component (and these SVG references/assets) to avoid keeping unused code and static files; otherwise the PR description should be updated to reflect that HomepageFeatures still exists.

The dark-mode overrides here target plain class names (e.g. .featuresSection, .featureCard, .techSection), but those classes are defined in index.module.css and applied via CSS modules, so the runtime class names are hashed and these selectors won’t match. As a result, the homepage will keep the light-section styles in dark mode. Move these dark-mode rules into index.module.css (e.g. :global([data-theme='dark']) .featuresSection { ... }) or apply a global class name on the elements and target that instead.

Suggested change

[data-theme='dark'] .featuresSection {

background: linear-gradient(180deg, #1a0f3e 0%, #0a0420 100%);

The transition rule block also uses .cosmicHero, .featuresSection, .techSection selectors which (as CSS-module classes) won’t match in global CSS. Even if moved/fixed, applying transitions to * under large sections can be expensive; consider limiting transitions to specific interactive elements (buttons/cards/badges) instead of all descendants.

+            <div key={idx} className={styles.techBadge} style={{ borderColor: tech.color }}>


techs.map((tech, idx) => ...) uses the array index as the React key. Since the key can be stable here (tech.name), prefer that to avoid unnecessary re-mounts if the list order ever changes.

Suggested change

<div key={idx} className={styles.techBadge} style={{ borderColor: tech.color }}>

<div key={tech.name} className={styles.techBadge} style={{ borderColor: tech.color }}>
