+// ✅ CORRECT - DOM update AND localStorage
+paper.classList.add('show-icons');        // Visual change (instant feedback)
+localStorage.setItem('cv-icons', 'true'); // Persistence (survives reload)
 
-// ❌ WRONG - Requires refresh
-localStorage.setItem('cv-icons', 'true');  // Only storage, no visual change

-**Why:** Users expect instant feedback. Any delay or refresh requirement feels broken.
+**Why both are needed:**
+- **DOM changes** = instant visual feedback (users see it immediately)
+- **localStorage** = state persists across page reloads (users don't lose their preferences)
+- Users need BOTH: instant feedback + remembered preferences

 ### Tech Stack
 
-**Runtime & Framework:**
-- ✅ Bun (JavaScript runtime)
-- ✅ Hono (Web framework)
-- ✅ HTMX (Hypermedia)
-- ✅ Hyperscript 0.9.14 (Event handling - LIMITED USE)
+**Backend:**
+- ✅ Go 1.21+ (Backend server)
+- ✅ Standard library `net/http` (HTTP server)
+- ✅ Go templates (Server-side rendering)
+
+**Frontend:**
+- ✅ HTMX (Hypermedia-driven interactions)
+- ✅ Hyperscript (Latest version - event handling)
+- ✅ Vanilla JavaScript (cv-functions.js - toggles, keyboard shortcuts)
+- ✅ Iconify (Icon system)
+
+**Testing:**
+- ✅ Playwright (E2E browser automation)
+- ✅ Bun (Test runner ONLY - NOT the runtime!)
+
+**Why Go:**
+- Fast compilation
+- Single binary deployment
+- Built-in templating
+- Excellent standard library
+- Strong typing
+- Cross-platform
 
 **Why HTMX + Hyperscript:**
 - Server-driven UI (hypermedia pattern)
 - Minimal JavaScript
 - Progressive enhancement
-- Real-time updates via SSE
-
-**Why Bun:**
-- Fast runtime
-- Built-in TypeScript
-- Native test runner
-- Single tool for everything
+- Real-time updates capabilities
