Remove unused import.
ModeToggle is imported but never used (its usage on Line 140 is commented out). This creates dead code.
Apply this diff to remove the unused import:
-import { ModeToggle } from "@/components/mode-toggle"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In app/page.tsx around line 10, the ModeToggle import is unused (its usage is
commented out); remove the unused import statement `import { ModeToggle } from
"@/components/mode-toggle"` from the file to eliminate dead code and update any
import ordering if necessary.

Inconsistent dark mode implementation.
Dark mode gradient classes (dark:from-zinc-900 dark:via-zinc-900 dark:to-black) are added throughout the component, but the ModeToggle for switching themes is commented out (Line 140). This creates an inconsistent state where dark mode styling exists but users cannot activate it.
Decision needed: Either enable the ModeToggle to make dark mode functional, or remove all dark mode classes to keep this PR focused on navbar height reduction as per the stated objectives.
🤖 Prompt for AI Agents
In app/page.tsx around lines 102 to 105, dark-mode Tailwind classes are present
but the ModeToggle component is commented out at line ~140, causing an
inconsistent UI; fix by either (A) re-enabling the ModeToggle: restore its
import and the commented JSX at line 140, ensure any theme provider or hook used
elsewhere is available (or add a simple useTheme/useEffect to persist class on
<html>), and verify the toggle updates the theme and that Tailwind's dark class
strategy is configured, or (B) remove all dark:... classes from this component
(search lines around 100–200) if you prefer to keep this PR focused on navbar
height; pick one option and apply only that change to maintain consistency.

Verify: Sticky header behavior added beyond PR scope.
The header is now sticky (sticky top-0 z-50), which was not mentioned in the PR objectives or issue #57. While this can improve UX, it may have unintended consequences:
- The sticky header continues to occupy vertical space during scroll
- This could partially negate the benefit of reducing header height
- Sticky positioning can affect scroll performance on some devices
Recommendation: Either document this as an intentional enhancement or consider removing the sticky behavior to keep changes focused.
Verify the impact of sticky header on the above-the-fold content goal:
#!/bin/bash
# Description: Search for any existing sticky header patterns or documentation about header behavior
echo "=== Checking for other sticky header usage ==="
rg -n "sticky" --type=tsx --type=jsx -g '!node_modules' -C 2
echo "=== Checking for header-related comments or documentation ==="
rg -n -i "header|navbar" --type=md -g '!node_modules' -C 3🤖 Prompt for AI Agents
In app/page.tsx around lines 107 to 116, the header element was made sticky
(classes: "sticky top-0 z-50"), which is outside the PR scope and may affect
above-the-fold layout and scroll performance; either remove the "sticky top-0
z-50" classes to restore original static positioning or, if keeping sticky is
intentional, add a brief comment above the header and update the PR description
and relevant documentation/issue (#57) to note the UI change and run the
suggested ripgrep checks to ensure consistency with existing sticky header
usage.

Uncomment or remove the ModeToggle placeholder.
The ModeToggle is commented out, leaving unclear whether dark mode should be enabled. This creates technical debt.
Options:
- If dark mode is desired: Uncomment this line and ensure all related theme code is functional
- If dark mode is out of scope: Remove this line, the import, and all dark mode styling classes
🤖 Prompt for AI Agents
In app/page.tsx around line 140 the ModeToggle component is left commented out,
creating ambiguity about dark mode support; either uncomment the ModeToggle
import and JSX at this location and verify the theme provider and related
CSS/classes (tailwind or CSS variables) are wired so dark mode toggles
correctly, or remove the commented JSX, delete the ModeToggle import and any
unused theme-related classes/styles and providers referenced only for it to
avoid dead code and styling artifacts.

Scope creep: Theme toggle component beyond PR objectives.
This component implements dark mode toggling functionality, which is not mentioned in the PR objectives (reduce navbar height) or the linked issue #57. The component is currently imported but not rendered in app/page.tsx (Line 140 is commented out), creating dead code and an inconsistent state where dark mode styles exist but the toggle is disabled.
Recommendation: Either remove this component and related dark mode code to keep the PR focused on navbar height reduction, or move the dark mode feature to a separate PR with proper documentation and testing.
Note: If you do intend to include dark mode, the implementation here is technically sound—the mounted guard (lines 12-13) correctly prevents hydration mismatches.

Scope creep: Theme provider beyond PR objectives.
Like the ModeToggle component, this theme provider implementation is part of dark mode functionality not mentioned in the PR objectives or issue #57. The implementation itself is sound—using explicit configuration with system theme detection is a good practice.
Recommendation: If dark mode is retained, this implementation is appropriate. Otherwise, remove it to maintain PR focus on navbar height reduction.
🤖 Prompt for AI Agents
In components/theme-provider.tsx lines 1-15 there is a NextThemes ThemeProvider
implementing dark-mode support which is out of scope for the navbar height
change; remove this file and any imports/usages (e.g., from root layout, _app,
or other components like ModeToggle) so the PR stays focused on navbar height
reduction; ensure you also delete or update any TypeScript/ESLint references and
exports to avoid broken imports.

Scope expansion: dark mode dependencies added beyond stated PR objective.
This commit adds @radix-ui/react-slot and next-themes along with theme-related components (theme-provider.tsx, mode-toggle.tsx), but the commit message focuses only on reducing navbar height. The dark mode feature is not mentioned in the stated PR scope. Consider isolating theme-related changes in a separate PR for clearer change tracking.
The pinned versions (1.2.4 and 0.4.6 respectively) are current and appear secure.
🤖 Prompt for AI Agents
In package.json around line 12, the PR unexpectedly adds theme-related
dependencies (@radix-ui/react-slot and next-themes) beyond the stated
navbar-height change; revert or remove these two dependency entries from this
branch and commit so the current PR only contains navbar-height changes, then
create a separate branch/PR that adds the theme-provider, mode-toggle, and the
two dependencies with a clear commit message describing the dark-mode feature;
ensure package.json, lockfile, and any newly added theme files are moved to that
separate PR.

What changed
Why
The navbar/header was occupying excessive vertical space, pushing main content below the fold.
This change improves usability and visual balance without altering functionality.
Screenshots
Before: Navbar consumes large vertical area
