This configuration option "ignoreDeprecations" is typically used to suppress TypeScript deprecation warnings in jsconfig.json, but the value "6.0" appears to be incorrect. This should either be removed if not needed, or set to a valid TypeScript version string if you're trying to suppress specific version deprecations. This may not have any effect or could cause unexpected behavior.

In `@jsconfig.json`:
- Around line 6-7: Update the jsconfig.json compiler option ignoreDeprecations
from "6.0" to "5.0" so it targets the TS version that introduced the option;
locate the ignoreDeprecations setting in jsconfig.json and change its string
value to "5.0".
In `@src/components/Footer.jsx`:
- Around line 74-83: The SocialLink component removes the native focus outline
(className contains outline-none) which harms keyboard users; update SocialLink
to use the project's focus-ring pattern instead: remove outline-none and add
focus-visible:ring classes (e.g., focus-visible:ring-2,
focus-visible:ring-primary, focus-visible:ring-offset-2) plus
dark:focus-visible:ring-yellow-400 or equivalent to match TimelineElement
buttons, ensuring the Link element (in SocialLink) has a clear visible ring on
keyboard focus while preserving hover/focus color classes.
In `@src/components/Header.jsx`:
- Around line 83-89: aria-expanded on the Popover.Button is hardcoded to false;
change to use the Popover render prop to reflect the actual open state. Wrap the
Popover's children in its render prop (e.g., Popover(({ open }) => ...)) and
pass aria-expanded={open} to Popover.Button (remove the hardcoded "false");
ensure any other conditional attributes/classes that depend on open use that
same open value.
In `@src/components/SectionHeading.jsx`:
- Around line 7-8: SectionHeading.jsx uses the class "animate-fade-in" but that
animation is not defined in Tailwind; add a "fade-in" entry under
theme.extend.animation and corresponding keyframes under theme.extend.keyframes
in tailwind.config.js so the class maps to an actual animation. In
tailwind.config.js extend theme, create an animation named "fade-in" (e.g.,
"fade-in": "fade-in 300ms ease-out both") and define keyframes "fade-in" with
from { opacity: 0; transform: translateY(10px); } to { opacity: 1; transform:
translateY(0); } so the "animate-fade-in" utility will work in
SectionHeading.jsx.
In `@tailwind.config.js`:
- Around line 23-45: tailwind.config.js declares custom fontFamily entries
"sans" (Inter) and "mono" (Fira Mono) but those fonts are not being loaded; load
them by adding a font import strategy and wiring it into the app: choose one
approach (e.g., add a Google Fonts <link> for Inter and Fira Mono in your
_document.jsx head, use next/font to load Inter and FiraMono and apply them to
the root layout, or add `@font-face` rules pointing to local font files in your
global CSS) and ensure the loaded font-family names match the keys used in
tailwind.config.js so that the "Inter" and "Fira Mono" entries are actually
available to the browser.
- Around line 69-73: The custom borderRadius overrides in tailwind.config.js
increased xl/2xl/3xl by 0.5rem which may break existing components using
rounded-2xl/rounded-3xl; inspect Card.jsx, Banner.jsx, CardEffect.jsx,
Header.jsx, and apply.jsx for visual regressions and either revert the custom
values to Tailwind defaults in tailwind.config.js or update the components to
use specific utility classes (e.g., rounded-xl, rounded-2xl, custom CSS classes
or new tokens) to match the refreshed design; run the app locally, review
affected components at common breakpoints, and adjust either the config or the
components so spacing and visuals match design specs.
🧹 Nitpick comments (6)
src/components/BrandingBackground.jsx (1)
2-22: Avoid SVG id collisions if this component renders more than once.
A staticid="brand-gradient"will collide across instances; use a unique id viauseIdand reference it in the fill URL.♻️ Suggested refactor
+import { useId } from 'react' + export default function BrandingBackground() { + const gradientId = useId() return ( <svg @@ - <defs> - <linearGradient id="brand-gradient" x1="0" y1="0" x2="0" y2="1" gradientTransform="rotate(20)"> + <defs> + <linearGradient id={gradientId} x1="0" y1="0" x2="0" y2="1" gradientTransform="rotate(20)"> <stop offset="0%" stopColor="#00843D" stopOpacity="0.15" /> <stop offset="100%" stopColor="#FED41E" stopOpacity="0.10" /> </linearGradient> </defs> - <rect width="1440" height="320" fill="url(`#brand-gradient`)" /> + <rect width="1440" height="320" fill={`url(#${gradientId})`} />src/pages/_app.jsx (1)
5-16: Good accessibility addition, but minor improvements possible.The skip-to-content link is a welcome accessibility enhancement. Two suggestions:
tabIndex={0}is redundant on anchor elements—they are focusable by default.- The component definition appears before the imports (Lines 17-22), which is unconventional and may confuse linters or tooling. Consider moving the
SkipToContentfunction after all imports.♻️ Suggested improvements
-function SkipToContent() { - return ( - <a - href="#main-content" - className="sr-only focus:not-sr-only absolute top-2 left-2 z-50 rounded bg-primary px-4 py-2 text-white dark:bg-primary-accent focus:outline-none focus:ring-4 focus:ring-primary-accent" - tabIndex={0} - > - Skip to main content - </a> - ) -} +function SkipToContent() { + return ( + <a + href="#main-content" + className="sr-only focus:not-sr-only absolute top-2 left-2 z-50 rounded bg-primary px-4 py-2 text-white dark:bg-primary-accent focus:outline-none focus:ring-4 focus:ring-primary-accent" + > + Skip to main content + </a> + ) +}src/components/Banner.jsx (1)
10-11: Consider reduced motion preferences for animated patterns.Both
Patterncomponents now haveanimate-pulse, which creates continuous animation. Users with motion sensitivity may find this distracting. Consider wrapping the animation in amotion-safe:variant.Additionally, Line 11 uses
sm:visible invisiblewhich is valid but could be clearer asinvisible sm:visiblefor reading order.♻️ Suggested change for motion sensitivity
- <Pattern className="absolute -top-28 left-0 w-full sm:left-3/4 sm:-top-10 sm:ml-8 sm:w-auto md:left-2/3 lg:left-auto lg:right-2 lg:ml-0 xl:right-auto xl:left-2/3 animate-pulse" /> - <Pattern className="absolute mt-2 -top-32 left-0 w-full sm:left-3/4 sm:top-36 sm:ml-8 sm:w-auto md:left-2/3 lg:left-auto lg:right-2 lg:ml-0 xl:right-auto xl:left-2/3 sm:visible invisible animate-pulse" /> + <Pattern className="absolute -top-28 left-0 w-full sm:left-3/4 sm:-top-10 sm:ml-8 sm:w-auto md:left-2/3 lg:left-auto lg:right-2 lg:ml-0 xl:right-auto xl:left-2/3 motion-safe:animate-pulse" /> + <Pattern className="absolute mt-2 -top-32 left-0 w-full sm:left-3/4 sm:top-36 sm:ml-8 sm:w-auto md:left-2/3 lg:left-auto lg:right-2 lg:ml-0 xl:right-auto xl:left-2/3 invisible sm:visible motion-safe:animate-pulse" />src/components/SectionHeading.jsx (1)
12-19: Simplify the nullish check.The explicit
number !== null && number !== undefinedcheck works but can be simplified tonumber != null, which covers both cases.♻️ Simplified null check
- {number !== null && number !== undefined && ( + {number != null && (src/components/TimelineElement.jsx (1)
14-14: Consider extracting the long className for readability.The button has comprehensive styling including hover, focus, and dark mode states—which is great for accessibility. However, the className string is quite long. Consider extracting common button styles to a shared utility or component for reusability across the codebase.
src/pages/index.jsx (1)
52-55: Complex responsive color logic may be hard to maintain.The heading uses different color tokens at different breakpoints:
- Mobile:
text-primary/ dark:text-primary-accent- md+:
text-primary-accent/ dark:text-secondary-darkThis inversion pattern is unusual and may lead to confusion. Consider simplifying to a consistent color scheme across breakpoints, or document the design intent if this is intentional.
