Purpose

Canonical specification for responsive-device-agnostic-layout requirements synced from OpenSpec change deltas.

Requirements

Requirement: Core layout is device-agnostic and responsive

The system SHALL render key surfaces (header, hero, feed, modal, footer, policy modals, and floating controls) responsively across mobile, tablet, and desktop viewports while preserving readability.

Scenario: Mobile layout behavior

• WHEN a user opens the site on a mobile viewport
• THEN content remains readable without horizontal overflow
• AND interactive controls including icon-only copy/back-to-top and policy modals 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

Scenario: Sticky shrinking glass header

• WHEN user scrolls downward
• THEN header remains sticky with slight height reduction, subtle elevation, and glass blur effect
• AND controls remain readable and usable at all breakpoints

Scenario: Sticky footer does not overlap core reading zones

• WHEN footer is sticky
• THEN content remains readable and interactive controls are not obscured
• AND mobile/tablet/desktop layouts stay overflow-safe
