+# Quick Task 260411-022: Fix Global Items Search Bar Layout
+
+**One-liner:** Collapsed three-section header (back link, title+subtitle, search) into a two-row compact layout with ArrowLeft icon, "Discover" back link, and inline title+search row.

+
+## Changes Made
+
+- **Back link:** Replaced `&larr; Dashboard` with `<ArrowLeft /> Discover` — clearer icon, correct label for Phase 27's landing page restructure
+- **Title:** Reduced from `text-2xl font-bold` to `text-lg font-semibold` and dropped the subtitle paragraph
+- **Search:** Moved inline with title using `flex flex-wrap items-center justify-between gap-4`. On mobile the search wraps below the title (`w-full sm:w-auto sm:max-w-xs`)
+- **Outer padding:** `py-6` → `py-4`
+- **Section margins:** Removed separate `mb-6`, `mb-8`, `mb-8` wrappers; replaced with `mb-3` (back link) and `mb-4` (title+search row)
+
