   product-grid.css — Diamonds Outta Dirt (Purpley Shop Product Grid)
   Path: /home2/asqrtyte/public_html/css/product-grid.css
   Purpose: product grid cards + images + badges + reveal items
   
   UPDATES (2026-02-16) — MOBILE CRASH & VRAM FIX:
   - ✅ CRASH FIX: Removed all global `will-change` declarations. 
   - iOS Safari crashes (WebKit Jetsam events) when `will-change` is applied to 
     multiple grid items combining `filter` and `transform`. 
   - ✅ VISIBILITY HARDENING: Ensured images remain fully opaque and don't collapse.
