+1. Define request/response types in `types.go`
+2. Write handler in `handlers.go` using `http.HandlerFunc`
+3. Add route in `routes.go`
+4. Write table-driven test in `handlers_test.go`
+5. Run `task check` before committing

+## Error handling pattern
+```go

+    return fmt.Errorf("descriptiveOperation: %w", err)
+}
+```
+Never log and return — do one or the other.
+
+## HTMX response pattern
+```go
+func (h *Handler) ListItems(w http.ResponseWriter, r *http.Request) {
+    items, err := h.store.List(r.Context())
+    if err != nil {
+        http.Error(w, "failed to list items", http.StatusInternalServerError)

+    h.templates.Render(w, "items/index", items)
