MODIFIED Requirements

Requirement: Core layout is device-agnostic and responsive

The system SHALL render key surfaces (header, hero, feed, modal, footer) responsively across mobile, tablet, and desktop viewports.

Scenario: Mobile layout behavior

• WHEN a user opens the site on a mobile viewport
• THEN content remains readable without horizontal overflow
• AND interactive controls remain reachable and usable

Scenario: Desktop and tablet adaptation

• WHEN a user opens the site on tablet or desktop viewports
• THEN layout reflows according to breakpoint design rules
• AND no key content or controls are clipped

Scenario: Readability-focused typography and contrast updates

• WHEN content is rendered in core reading surfaces
• THEN typography and color choices improve baseline readability
• AND updates remain compatible with responsive behavior across breakpoints
