   MOCKLAB — shop catalogue page.
   Layout follows the creatsy.com/mockups pattern: dark hero with in-banner
   search, toolbar with filter drawer + sort, 4-up product wall with thumbnail
   rails and coral price panels, then supporting info sections.
   Loaded after styles.css and content.css so it can refine the chrome.
