 - `avatar-inset-28` is a source-faithful static fixture for the exact 32px trigger and 32px-to-24px artwork change; source tests and component code remain authoritative.
 - `danger-button-32` has no before/after capture yet. The implementation proof is `tests/lib/danger-button.test.ts` plus the compiled CSS, which emits no `.text-destructive-foreground` rule before the change and `color: var(--destructive-foreground)` after it. Capture light and dark dialogs for the SSE discard, stop-KMS, force-delete, object delete, and a `dialog.error` confirm before citing this key.
 - `account-2fa-29` is a set of live runtime captures, not fixtures: a debug RustFS server with `RUSTFS_IAM_MASTER_KEY` set, this branch on `pnpm dev`, root identity, viewport 1585x1202 CSS px (the setup-dialog frame is 628 CSS px). It covers 2FA off/on, the setup QR, the recovery-code dismissal guard, the profile page, and the login second-factor step. It does **not** include a mobile viewport or a `main`-branch before-capture of the account menu; the responsive rules and the removed administrator gate are covered by source tests, which remain authoritative for those two.
+- `table-catalog-disable-34` captures the running Next.js S3 Tables page at 1440x1000 with mocked catalog responses and an enabled bucket. The before capture uses `main`; the after capture uses the capability-gated disable action. Browser checks cover old-server compatibility, permissions, cancellation, conflict retry, disable and re-enable, and mobile/dark confirmation. These are Console checks with controlled responses; backend safety is verified separately.
 - The full on-disk mapping is maintained in the screenshot manifest next to the image archive.
