Findings from a full frontend audit (static read + live instrumentation of
production). This covers the "bleeding" and performance phases.
Bug fixes:
- StatsPanel branch collapse/expand never re-rendered. Two Svelte 5 defects:
$state(new Set()) is not proxied (proxy.js bails on non-object/array
prototypes), so .add()/.delete() were untracked; and the Svelte 4
`x = x` reactivity idiom is a no-op in runes mode, where sources use a
strict `equals` comparator. Switched to SvelteSet and dropped the
self-assignment. Verified: aria-expanded now flips and rows 28<->24.
- The closed stats panel's gold box-shadow (8px offset + 80px blur) bled
~88px past its right edge, painting a permanent olive stripe down the
left of the viewport on every page view. Offset the closed transform
past the shadow.
- data.ts shipped a placeholder repoUrl (github.com/yourusername/...), a
live 404 on the node describing this very site. Also removed the
"Tailwind CSS" techStack claim; it is not a dependency of this project.
Performance:
- nodes.ts awaited Assets.load() inside the node loop, serialising ~56 icon
round-trips before the tree could render or accept input. Now one
parallel batch. Measured: all 78 tree icon requests start at ~28ms and
complete within ~618ms.
- isLoading was cleared right after app.init(), before a single texture
existed, so the spinner resolved onto an empty screen. Moved to after
the scene graph is built.
- Renderer left antialias on (costly, ~no benefit on soft glow circles)
and resolution/autoDensity at defaults (blurry on HiDPI). Now
antialias:false, resolution:min(dpr,2), autoDensity, high-performance.
- cacheAsTexture on the fully-static gradient (16 full-screen fills) and
vignette (13); interactiveChildren:false on background containers.
- Dust ticker allocated a fresh closure per frame via forEach; replaced
with a named function and an indexed loop.
Dead weight:
- static/{headshot,profile}.jpg.original (8.6MB, 83% of the static payload)
were committed and deployed verbatim by adapter-static, publicly
fetchable and referenced by nothing. Moved to a gitignored assets-src/
so the full-res sources stay on disk without shipping.
- precompress:true so nginx gzip_static/brotli_static have siblings to
serve (the origin currently sends everything uncompressed).
build/ 11.13MB -> 3.7MB. JS wire 727.6KB raw -> 232KB gzip / 202.7KB brotli.
svelte-check clean, 14/14 tests pass.
Note: the matching nginx change lives in the gitignored homelab/default.conf
and must be applied to the container separately.

sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create my-app
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
