Enhance Existing PWA Design

I already have a progressive web app up and running on a PHP backend and the core template is in place. What I need now is a small round of feature additions that focus squarely on the front-end look and feel. The task is essentially a series of CSS edits—tweaks that refine layout, spacing, and any visual inconsistencies that slipped through the template’s default styling.

You’ll receive the current codebase and template so you can jump straight into editing. I expect clean, well-commented CSS and any supporting assets you create to slot neatly into the existing structure without breaking the service worker or other PWA fundamentals.

Acceptance is simple: once your changes are merged, the app should compile without errors, render consistently across modern browsers, and reflect the requested style updates throughout every screen and state—online or offline. If that sounds straightforward, I’m ready to share the repo and get this wrapped up quickly.
