## MODIFIED Requirements

### Requirement: Footer exposes policy navigation links

- **THEN** footer remains sticky at viewport bottom
- **AND** footer height stays compact enough to avoid readability obstruction

#### Scenario: Floating back-to-top island
- **WHEN** page is scrolled beyond initial viewport
- **THEN** a floating back-to-top control is visible
- **AND** activating it returns viewport to top smoothly
