graph.refresh() sets three-forcegraph's _flushObjects flag, which destroys and recreates every Three.js object in the scene. Desktop GPUs hide the rebuild inside a frame; on mobile it reads as a full-screen flash on every select, deselect (background tap), SSE pulse, and 2s fade tick. Replace all refresh() call sites with repaint(): re-assigning fresh closures for the selection/pulse/chain-dependent accessors (nodeColor, linkColor, particle trio) takes the lib's in-place material/particle update path — objects survive, no flash. linkWidth is the one visual accessor whose prop-change DOES flush link objects (cylinder geometry is in the clear list), so width is now static per edge type and chain emphasis rides on full-alpha red + particles, as it already did visually. Also kill the gray mobile tap-highlight on the canvas. Reported by Dave on mobile right after PLAN-1730 shipped.
Pad Web UI
SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.
Development
npm install
npm run dev # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build # Production build to build/
npm run check # Type checking with svelte-check
When developing, run the Go backend separately with make dev from the project root.
Building for Production
Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.
