 **How to apply:** after running curl-based API tests that mutate state, restart the
 api-server workflow before screenshots/handoff so the user sees a clean seeded demo.

+## Donate e2e: use OPEN cases only
+Seed cases req-001..req-006 are already in later pipeline stages (fully funded,
+remaining 0). The donate page clamps any donation to the case's remaining target, so
+on those cases the amount silently becomes 0 and the donate POST returns 400 — you
+never reach the success screen. For donation/success-screen e2e, use a `published`
+case with remaining > 0 (e.g. req-007, req-012..req-017).
+**Why:** cost 3 failed test runs chasing a non-bug. The clamp + funded-seed
+interaction is not obvious from the UI alone.
