Two robustness fixes behind the recurring "folder upload stuck at ~93%" reports.
1. Skip non-regular files up front. A copied s6/runit service tree contains
FIFOs (e.g. supervise/control named pipes) that report a size but BLOCK
FOREVER when the browser reads them — the deterministic ~8-files-short that
no retry/watchdog tweak could fix. uploadBatch/uploadTree now probe each
file's first chunk against a 3 s timeout (partitionReadable), upload only the
readable ones, and report the rest: "N uploaded · M skipped (not regular
files)". Progress runs over the uploadable count, so it reaches 100% instead
of parking at 93% while a lane hangs on a pipe.
2. Auto-reload on a new deploy. svelte.config.js polls _app/version.json
(60 s); the root layout reloads itself when the deployed build changes —
unless an upload is in flight — so an open tab can't keep running stale code
after a rebuild (the recurring "my fix isn't applied" trap).
npm run check: 0 errors, 58 tests pass.

The app is a pure client-rendered SPA (ssr=false, adapter-static), so until the
JS bundle downloads, parses and mounts, the page is blank — only then does the
layout's own loading state appear. True route prerendering would mean turning on
SSR, an architectural change at odds with the SPA design.
Instead, bake a tiny boot splash into the shell (`app.html`): a centered spinner
that paints the moment the HTML is parsed — before the app bundle or its CSS
load — covering the blank gap. The root layout removes `#app-splash` the instant
it mounts (before `session.load`), so public routes like /login (which render
without waiting for the session) appear immediately and protected routes hand
off to their own loading UI. `light-dark()` plus early `color-scheme` rules make
the splash match the resolved theme (incl. the saved override), so there's no
colour flash when the app CSS arrives; it respects `prefers-reduced-motion`.
Pure HTML/CSS in the shell — no new requests, no JS framework on the critical
path, ~0.6 KB in index.html. Verified on the real static-dist build in headless
Chromium: the shell ships `#app-splash`, the layout removes it after mount, the
app renders, and there are no runtime errors.
