📝 Walkthrough

Summary by CodeRabbit

• Accessibility

  • Improved support for reduced-motion preferences by disabling nonessential animations.
  • Added larger touch targets and removed mouse-only guidance on touch devices.

• Responsive Design

  • Improved the knowledge graph experience on mobile and narrow screens.
  • Added responsive layouts for portrait and landscape orientations.
  • Enabled scrolling and size limits for mobile header and information panels.
  • Optimized graph sizing to use the available screen height and width.
  • Hid nonessential content on smaller screens.

Walkthrough

The graph UI now supports mobile viewport sizing, responsive panels, touch-friendly controls, landscape layouts, and reduced-motion preferences. The source template and generated knowledge graph receive matching CSS updates.

Changes

Responsive graph interface

Layer / File(s)	Summary
Viewport sizing foundation docs/index.html, scripts/build_knowledge_graph.py	The page prevents automatic mobile text scaling. The graph uses full width with 100dvh and a 100vh fallback.
Responsive and accessibility styles docs/index.html, scripts/build_knowledge_graph.py	Mobile and landscape layouts constrain and scroll panels, enlarge touch targets, hide nonessential content, remove mouse hints on touch devices, and disable motion when requested.

Estimated code review effort: 2 (Simple) | ~15 minutes

Poem

I’m a rabbit with a graph to hop,
Mobile panels scroll instead of stop.
Touch targets grow, hints fade away,
Reduced motion keeps hops at bay.
Wide or narrow, the view stays bright!

In `@scripts/build_knowledge_graph.py`:
- Around line 516-530: The landscape responsive CSS in
scripts/build_knowledge_graph.py lines 516-530 allows `#header` and `#info-card` to
overlap on narrow viewports; constrain both panel widths to the available half
viewport, such as using a min(320px, calc(50vw - 20px)) width. Regenerate
docs/index.html lines 339-353 from the updated template so the generated output
contains the same fix.
- Around line 541-548: Update scripts/build_knowledge_graph.py lines 541-548 to
use matchMedia('(prefers-reduced-motion: reduce)') when configuring directional
particles and Graph.cameraPosition, setting both values to 0 when reduced motion
is active; then regenerate docs/index.html lines 364-371 so the generated output
matches the template.
