Modern WordPress website Design

I’ve set up a WordPress install but now need it styled into a clean, modern vedic website that highlights written articles. The layout should feel contemporary—think generous white space, crisp typography, and a responsive grid that adapts flawlessly on mobile and desktop. The website is https://vedartham.com/

Here’s what I need done:
• Select or build a lightweight theme, then customise colours, fonts and spacing so the reading experience feels uncluttered and professional.
• Configure homepage and post templates for text-focused articles, including a featured-post area and clear category navigation.
• Optimise performance (caching, image compression, minimal plugins) so pages load quickly.
• Set up essential blog elements: SEO-ready structure, social sharing, email signup section and an easy-to-use editor view so I can publish new text pieces without touching code.

Once the design is in place, walk me through any custom blocks or settings you’ve added so I can maintain everything myself. Deliver the finished site ready for launch on my existing host.
