My Shopify store already shows a banner at the top of each collection, but the current theme constrains it within the page margins. I’d like the banner to stretch edge-to-edge on every collection page so it matches the fluid look of the rest of the site. You’ll receive the approved banner mock-ups and any image assets, so there’s no design work needed—this task is purely implementation. Please update the theme’s Liquid, CSS, and any relevant sections/snippets so that: • All existing and future collection pages automatically display the banner at full browser width, regardless of screen size. • No other layout elements (product grid, filters, etc.) are pushed out of alignment. • My original desktop and mobile designs render exactly as supplied. Once you’re done I’ll run a quick check across multiple devices; if everything looks pixel-perfect and the layout stays responsive, the job is complete.
