• Expand the <details> block and verify the curl command is readable and the Copy button works
• Navigate to Integrations → PM → Step 5 (Webhooks); verify "Create Webhook" button appears below the collapsible curl instructions
• For a project with stored Trello credentials, navigate to PM → Step 2 (Credentials); verify green "Credentials stored" banner appears at the top of the step
• Verify dark mode styling is preserved across all modified sections
• All unit tests pass (npm test — 5480 tests)
• TypeScript type check passes (npm run typecheck)
• Biome lint passes (npm run lint:fix)

LGTM — Clean UI reordering with no logic changes. The curl instruction blocks are correctly moved above their respective buttons and wrapped in collapsible <details> elements, directional text ("above" → "below") is consistently updated across all three files, and dark mode styling is preserved. All CI checks pass.
