…Tcloud?" post (#3228)

## Description

This PR contains a style change for the blog hero image and minor copy
changes to the "What is WATcloud?" blog post.

### Style change

Before/after on screens with small width:
<img width="2672" alt="image"
src="https://github.com/user-attachments/assets/c5123c81-e38e-4a97-b34a-0972a8fb1832">

Also removes unnecessary image size changes on certain browsers (like
brave on iPadOS) that change window height on scroll:

-WATcloud's mission is to make computing resources available to everyone in an easy and fair way.
-Over the past four years, we have continuously iterated on both the hardware and software that comprise our cluster.
-On the hardware side, WATcloud consists of servers, switches, IP-KVMs[^ip-kvm], and other peripherals that form our compute cluster.
-On the software side, WATcloud encompasses over 3,000 pull requests and tickets in our internal monorepo,
-along with over 40 satellite repositories ranging from bug-fixing forks of open-source projects to custom tools.

+On the hardware side, WATcloud includes servers, switches, IP-KVMs[^ip-kvm], and other peripherals that form our compute infrastructure.
+On the software side, we have developed a variety of systems for managing the compute cluster, user provisioning, and auxiliary services.
+These efforts encompass over 3,000 pull requests and tickets in our internal monorepo, along with more than 40 satellite repositories—ranging

 Throughout the years, we've learned and grown immensely, and we're excited to share our journey with you.

 Over the next few blog posts, we'll be sharing the architecture of WATcloud in its current state and how we got here.
 Here's a list of topics we'll be covering:
 - Compute cluster hardware setup

+- Operating system, hypervisor, and virtual machine configuration
 - Distributed storage configuration
 - Network configuration
 - Compute cluster provisioning pipeline
