   - Migration `migrate_system_settings_login_captcha()` adds the column with `DEFAULT TRUE`
   - Audit-logged when changed (same pattern as other General settings)
 
+### Fixed
+- Login page layout broken when flash messages were present (e.g. "You have been logged out"):
+  - `bc-main-auth .bc-content` now uses `max-width: 480px; margin: 0 auto` as a centered column instead of `align-items: center` on a flex container (which caused Bootstrap `col-md-4` percentage widths to collapse)
+  - `login.html`: replaced `row justify-content-center / col-md-4` with a plain `<div>` — the parent CSS column handles centering
+
 ### Changed
 - Sandbox banner: semi-transparent (`rgba(220,53,69,0.45)`) instead of solid red
