Fix Safari CSS & Optimize Speed

My WooCommerce store obsco.ca renders perfectly in Chrome, yet Safari throws the layout off. The two areas that visibly drift are the sidebar navigation and the footer section; everything else seems fine at a glance, but I’m not 100 % sure there aren’t other hidden issues in Safari.

Here’s what I’ve done so far:
• Disabled both CSS and JS minification in the LiteSpeed Cache plugin, which partially corrected the sidebar but left small alignment quirks behind.
• Tweaked a few PHP snippets and CSS with ChatGPT’s help.

What I need now is a developer who can:

— Pin-point and correct the remaining cross-browser CSS issues so the sidebar and footer line up identically in Safari without breaking the current look in Chrome or other browsers.
— Keep the scope on fixing alignment only (no redesign work for now).
— Review the current LiteSpeed Cache settings and suggest any cache, compression, or asset-loading adjustments that could squeeze a bit more speed out of the site. Our hosting resources are basically maxed out, so advice on realistic gains or alternative setups will be appreciated.

I’ll provide before/after screenshots, admin access, and any additional details you need. Once everything displays consistently in Safari—and page speed scores show at least a small bump—I’ll sign off on the work.
