Reviewer's Guide

This PR updates the mobile navbar overlay so that link clicks trigger an instant-close mode (no transition) just before navigation, and ensures that subsequent openings restore normal animated behavior, including a forced reflow to reliably apply the instant-close style.

File-Level Changes

Change	Details	Files
Add an instant-close mode for the mobile overlay when a navigation link is clicked, and ensure transitions are reset on subsequent openings.	On hamburger click, explicitly remove the 'instant-close' class from the overlay before toggling the menu state so normal transitions apply when opening. When handling link clicks that trigger navigation, add the 'instant-close' class to the overlay before closing to bypass transitions and make the overlay disappear immediately. After closing the overlay in instant-close mode, force a reflow via 'void overlayElement.offsetHeight' to ensure the browser applies the updated styles and future openings animate correctly. Define a '.mobile-overlay.instant-close' CSS rule that disables transitions and hides the overlay immediately using 'transition: none' and 'visibility: hidden'.	src/components/layout/Navbar.astro

📝 Walkthrough

Walkthrough

The mobile navigation overlay now supports immediate hiding via an instant-close class. When the menu opens, the class is removed to restore normal transitions. When a navigation link is clicked, the class is applied and a layout reflow is triggered before the overlay closes, ensuring instant visual feedback without transition delay.

Changes

Mobile overlay instant-close behavior

Layer / File(s)	Summary
Instant-close overlay styling and toggle logic src/components/layout/Navbar.astro	CSS adds .mobile-overlay.instant-close to disable transitions and hide immediately. Script removes the class on menu open, adds it on navigation link close, and forces reflow via offsetHeight to ensure the instant-close takes effect before state updates proceed.

Poem

🐰 Hop, click, and whoosh—the overlay flies,
No silly delay, just swift goodbyes,
A touch of the class, a reflow command,
The menu obeys with a snap so grand!

Hey - I've left some high level feedback:

• Consider adding a short code comment near void overlayElement.offsetHeight; to explain that it’s intentionally forcing a reflow for the instant-close behavior, since this pattern can be confusing to future readers.
• Review whether .mobile-overlay.instant-close needs !important on both transition and visibility, or whether scoping/selector specificity could be adjusted instead to avoid relying on !important.
• Double-check all code paths that close or reopen the mobile overlay (e.g., clicking the overlay itself, escape key handlers) to ensure they consistently add/remove the instant-close class so that the overlay doesn’t get stuck in a no-transition state.
