ModelBreeder.com v2.5.0 Layout Density Implementation Notes

This release fixes the visual-density issues reported on the Apex Multi Model page.

Observed layout problems

• Article titles were scaled for marketing hero pages rather than long technical titles.
• The article title was constrained to a short line length, forcing unnecessary wrapping.
• The article layout used a fixed article width and justify-content: space-between, which created a large empty gutter between the table of contents and content on wide screens.
• The shell left usable horizontal space unused while dense technical content stayed cramped.
• The header navigation could overflow before the mobile menu breakpoint.
• Code blocks, diagrams, tables, and tools needed a clearer rule for using more width than ordinary prose.

Implemented fixes

• Reduced article and page hero type scale.
• Increased title max line length and enabled balanced wrapping.
• Converted article layout to a liquid grid: compact sidebar plus fluid article area.
• Removed the accidental space-between gutter.
• Capped prose width for readability while allowing diagrams, tables, code, tools, and evidence panels to use full article width.
• Made the desktop header collapse earlier so it does not cause body-level horizontal overflow.
• Added a public operations page documenting the layout-density contract.
• Added an active .uai memory record and Totem note requiring better use of screen space.

Design principle

Use useful density: fewer dead gutters, fewer oversized headings, more visible working content, and liquid layouts that adapt to the available surface.
