Ecosystem Hardening: Mobile First

Contracts in Your Pocket

The initial ACM interface was optimized for the power user at a wide desktop monitor. As our client base expanded to include field-based legal counsel on tablets and associates reviewing contracts on phones, the mobile experience became a critical gap.

This sprint delivered targeted hardening for ultra-narrow viewports.

Specific Viewport Failures

  • Sidebar Overlap: The collapsible sidebar was not fully collapsing to icon-only mode at the 640px breakpoint, causing it to overlap the main content area.
  • Typography Stack Collapse: The responsive typography scale was collapsing too aggressively, with some metadata labels dropping below 10px — illegible without zooming.
  • Horizontal Scroll Contamination: Several data grid components had minimum column widths that exceeded the viewport, introducing unwanted horizontal scroll.
  • Touch Target Undersizing: Interactive elements in the audit timeline had touch targets smaller than the 44x44px minimum recommended by WCAG.

The Fixes

  1. 1.Snap-to-Icon Threshold: The sidebar collapse breakpoint was tightened to 720px, with a smooth transition animation.
  2. 2.Typography Floor: A minimum font size floor of 11px was introduced via a CSS custom property, preventing the scale from collapsing below legibility.
  3. 3.Grid Column Flexibility: All data grid columns were refactored from fixed min-width values to minmax(0, 1fr) flex-grid definitions.
  4. 4.Touch Target Padding: Audit timeline controls were wrapped in invisible padding zones to achieve the 44x44px touch target standard.

Agentic Intelligence, Any Screen

The mobile hardening sprint ensures that the ACM platform delivers a consistent, premium experience regardless of device. Contract intelligence should not have a minimum screen-size requirement.
