Summary
Add CSS-only skeleton placeholders on the Explore page, shown while HTMX loads filtered results or another page.
Skeletons use the same grid as the real cards, so there is no layout jump when results arrive.
prefers-reduced-motion users see static placeholders (no shimmer).
The skeleton container is aria-hidden; the existing #list-status live region still announces loading to screen readers.
Implementation note

The issue suggested hx-on handlers to dim #issue-list. Instead I hide the list with a CSS rule (body:has(#skeleton-loader.htmx-request) #issue-list) while the skeleton is visible, so no JavaScript is needed. Happy to switch to the opacity approach if you prefer.

Testing
pytest: 28 passed.
Tested filter changes and pagination with Slow 3G throttling.

Closes #27

Clean, JS-free and accessible. Matching the real card grid and covering pagination is a great touch. ✅

Merged! 🎉 Thank you again @sssimransingh26-bit. Two solid PRs in two days! The CSS-only approach with :has() is elegant, and testing on Slow 3G is exactly the mindset OpenToAll is built around (real-world connections). The Explore page feels much smoother now.
