Changelog 2026-03-07 (Phase 3: Large-Screen Layout Refinement Continuation)

Article content

Changed

• Refined large-screen container and grid sizing for better width utilization at 1200px+ and 1580px+ breakpoints.
• Added sticky sidebar behavior on desktop so operational signals stay in view while scanning long post lists.
• Introduced ultra-wide two-column packing for sidebar tab panels to reduce vertical scroll churn and improve scan speed.
• Added explicit card hooks (now-shipping-card, quick-links-card) to support predictable large-screen layout targeting.
