enhance blog and collection pages

Description:
Currently, the Blog and Collection pages are very basic with minimal content styling and layout. To make the website more engaging and professional, we should enhance these pages with improved design, structure, and interactivity.

📌 Proposed Improvements
Blog Page

Add blog cards or grid layout instead of a single text block.

Include blog title, thumbnail image, short description, read more link.

Improve typography (font size, spacing, line height).

Add hover effects on blog cards for interactivity.

Collection Page

Display collections in a responsive grid layout.

Each collection should have an image, title, price (if applicable), and description.

Add filtering/sorting options (e.g., by category, price, popularity).

Ensure mobile responsiveness.
