- .container redefined on Carbon tokens (was Bootstrap's class — pages had
no edge padding after the Bootstrap removal)
- landing tiles use cds-clickable-tile and — critically — matching closing
tags: the fingerprint tile was parsed as NESTED inside the cropper tile
(mismatched </cds-tile>), painting it on top and swallowing clicks
- landing header reflects the active session (user chip + Sign out instead
of Sign in)
- vertical rhythm: larger panel padding, row gaps and section margins
