Copilot was unable to run its full agentic suite in this review.
This PR simplifies fullscreen handling and updates split-layout sizing styles in the code editor page.
Changes:
- Replaced state-based fullscreen toggling with a
handleFullscreenTogglethat calls the browser Fullscreen API. - Updated action handlers (command palette, “More” sheet, toolbar button) to use
handleFullscreenToggle. - Adjusted split-pane sizing styles to always set explicit
width/heightinstead of relying on{ flex: 1 }.

Closes #98
Description
This PR resolves critical layout breakage on mobile devices caused by redundant code duplication in
app/page.tsx. The file contained duplicate state declarations, effect hooks, and event listeners that were creating React state conflicts and memory leaks.Problem
The codebase had accidental code duplication (likely from a merge conflict) that introduced three major issues:
resize,mousemove,touchmove, andfullscreenchangelisteners were registered twice, causing memory leaks and performance degradation.isMobilestate declarations existed, causing the responsive layout logic to reference an undefined state, resulting in complete layout breakage on mobile devices.Symptoms
