Task 3's review surfaced that the plan's original vi.importActual-based
mocking for Shop.test.tsx/Home.test.tsx/Book.test.tsx would execute the
real data-layer modules, which import the real Supabase client and
construct it at module-load time via createClient(VITE_SUPABASE_URL,
...) -- throwing "supabaseUrl is required" in a test env with no .env
file, before the test even runs.
Switched all three to mock ../lib/supabase directly instead, matching
the pattern Task 3's own products.test.ts already uses successfully.
Also fixed 3 occurrences of `err instanceof Error ? err.message :
String(err)` in the planned Shop.tsx/Home.tsx/Book.tsx error handling
-- fetchProducts/fetchServices throw the raw Postgrest error object
(not necessarily an Error instance), so this would have rendered
"[object Object]" instead of the real message in the mocked test
scenario.
