Act as a Senior Web Designer & Speed Optimization Expert for Blogger (Blogspot).

I need to fix UI bugs, boost load speed to 100%, and add high-trust elements to my gaming top-up store template.

FIXES & UPGRADES NEEDED:

1. Fix Post Title Bug: In the post loop template (<b:loop>), replace hardcoded/header titles so the real post title (<data:post.title/>) displays instead of the word "Posts".

2. Hide Floating Pagination: Provide CSS to completely remove/hide the orphan floating pagination button (e.g., the standalone "1" box).

3. Product Card UI Upgrade:

   - Full-width responsive layout for product cards.

   - Neon border glow on hover/active.

   - Clean spacing between image, title, badges, and "BUY NOW" button.

4. Trust Elements:

   - Add a responsive payment icons strip (eSewa, Khalti, IME Pay logos) placeholder right below the header/hero area.

5. Speed Optimization:

   - Provide lightweight CSS/JS cleanup snippets for Blogger to disable render-blocking default scripts.

   - Implement native image lazy-loading (`loading="lazy"`).

Please output clean, copy-pasteable CSS and XML code blocks with instructions on where to place them in Blogger's 'Edi

t HTML' section.
