feat(web): the console asks its own questions
Follow-up to a85e8452, closing the three items that sweep flagged and left.

SIXTEEN BROWSER DIALOGS, GONE. Every destructive action in an otherwise fully
branded console handed off to `window.confirm` — a grey OS box with the page's
URL in it, no brand, no red on a delete, and untouchable by any story or
screenshot, which is part of why it survived this long.

They are replaced by one promise-based surface (components/dialogs.tsx) rather
than a dialog per call site. The native calls were EXPRESSIONS — `if
(!confirm(…)) return;` — threaded through mutation handlers; rewriting each into
"hold the pending action in state, render a dialog, run it from onConfirm" would
have put dialog machinery in every section file and turned each linear handler
inside out. Returning a promise keeps them the shape they already were, and it
is what let the navigation guard come along too: TanStack's `shouldBlockFn`
accepts `Promise<boolean>`. `beforeunload` necessarily stays native — a reload
is the browser's dialog to draw, and it will not wait on ours.

No warning copy was rewritten. Each message was SPLIT at its existing sentence
boundary: the question becomes the dialog's title, the consequence its body,
and "Continue?" is dropped where the affirmative button now carries the verb
("Delete", "Uninstall", "Unpair", "Stop every session"). 16 new keys, en and de
in parity at 629.

Verified by driving the real dialogs in a headless browser — all seven contract
checks pass, including the two that would be invisible until they bit: Escape
SETTLES the promise (an unsettled one would hang a mutation handler forever with
no error), and a cancelled prompt resolves null rather than "", so a caller can
still tell "backed out" from "cleared the field".

FOUR OF THE SEVEN NUMERIC FIELDS became InputNumber; three deliberately did not,
and now say why in place. The layout X/Y pair had a real defect: a screen left
of the origin has a negative coordinate, and `Number("-") || 0` rewrote the lone
minus sign to "0" before the digits could be typed. Measured on the built page:
the field can now be emptied to retype instead of snapping to its floor, and 900
in a 1..=16 field clamps to 16. The three left alone cannot take it — the grace
seconds field writes to the HOST on blur (InputNumber commits while typing, so
its clamp would race the apply), and the library's year/players are OPTIONAL,
where `value: number` has no way to say "unset" and would invent a year for
every entry without one.

The select's highlighted row moves off @unom/ui's neutral grey onto the brand
wash the nav and the preset cards already use.

The Displays story earned its keep immediately: adding `useDialogs` to that page
broke it in Storybook, because the provider was mounted in __root and nowhere
else. It belongs beside the other app-level providers in .storybook/preview.

punktfunk web — management console

The browser UI for the punktfunk host's management REST API (crates/punktfunk-host/src/mgmt.rs, OpenAPI at api/openapi.json). It shows live status, host capabilities, paired clients, the pairing-PIN flow, and session controls.

Stack: TanStack Start (full SSR) on Bun via Nitro v2 (bun preset) · React Query through orval codegen from the OpenAPI spec · @unom/ui — the shared punktfunk/unom design system the marketing site + docs are built on (Tailwind v4, animated components on the violet brand over dark chrome) · Paraglide i18n (en/de). Package manager + runtime: Bun.

The @unom registry mapping lives in .npmrc; the auth token comes from ~/.npmrc (or a CI secret).

Develop

# from web/  — Bun is the toolchain (https://bun.sh)
bun install               # runs `prepare` → codegen (orval + paraglide)
bun run dev               # http://localhost:47992

# The dev server proxies /api → https://127.0.0.1:47990 (the host's mgmt API; it serves HTTPS
# with the host's self-signed identity cert — the dev proxy uses `secure: false`).
# Point it elsewhere: PUNKTFUNK_MGMT_URL=https://<host>:47990 bun run dev

Start a host with the management API up:

# from the repo root — `serve` brings up the native punktfunk/1 plane + the mgmt API (the console
# only needs the mgmt API; add --gamestream too if you also want the Moonlight surface):
WAYLAND_DISPLAY=wayland-kde XDG_CURRENT_DESKTOP=KDE \
  cargo run -rp punktfunk-host -- serve
# loopback :47990, no token (a token is mandatory for non-loopback binds).

The management token is server-side only — set PUNKTFUNK_MGMT_TOKEN in the console's environment and the BFF injects it when proxying (server/routes/api/[...].ts). It never reaches the browser, so there is no token field in the UI; the browser only ever holds the session cookie.

Build & run (Nitro + Bun)

The console runs on bun (Bun.serve is a Bun API — node can't run it): Nitro's bun preset plus a custom entry (nitro-entry/bun-https.mjs) that calls Bun.serve({ tls }), so it serves HTTPS (HTTP/1.1 over TLS) with the host's own identity cert (the cert native clients already pin). One trust anchor across the data plane, the mgmt API, and this console. (No HTTP/2 — Bun.serve has no h2 server — and no HTTP/3, which a browser won't speak against this self-signed, no-SAN host cert; a browser-trusted, SAN-matching cert + a fronting server would be needed, out of scope for a LAN console.)

bun run build             # → .output/  (Nitro `bun` preset + our Bun.serve TLS entry)
PORT=47992 HOST=0.0.0.0 \
  PUNKTFUNK_UI_PASSWORD=PUNKTFUNK_MGMT_TOKEN=\
  PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 \
  PUNKTFUNK_UI_TLS_CERT=~/.config/punktfunk/cert.pem \
  PUNKTFUNK_UI_TLS_KEY=~/.config/punktfunk/key.pem PUNKTFUNK_UI_SECURE=1 \
  bun run start           # = bun run .output/server/index.mjs
# PUNKTFUNK_UI_TLS_* unset ⇒ plain HTTP (local dev); both set ⇒ HTTPS (HTTP/1.1 over TLS).
# The host's self-signed mgmt cert is accepted only for the proxy's loopback hop, scoped in code
# (Bun per-request TLS: server/routes/api/[...].ts) — no process-wide NODE_TLS_REJECT_UNAUTHORIZED.
# See .env.example.
bun run lint              # tsc --noEmit

The built Nitro bun server SSR-renders the app and is the only thing exposed on the LAN. Run it on the same box as the host; it serves the console over HTTPS on :47992 (or $PORT).

Auth (backend-for-frontend)

Single-user, login-gated. Config via env (see .env.example):

  • The console requires a login (PUNKTFUNK_UI_PASSWORD). On success the server sets a sealed session cookie (h3 useSession, AES-GCM). server/middleware/auth.ts gates every request — pages redirect to /login, /api returns 401 — and fails closed (503) if PUNKTFUNK_UI_PASSWORD is unset, so a misconfigured LAN server admits no one.
  • The bearer-token admin surface of the management API is loopback-only — the host honors a bearer token only from a loopback peer, so the admin API is never LAN-exposed. The web server holds PUNKTFUNK_MGMT_TOKEN server-side and injects it when proxying /api/**PUNKTFUNK_MGMT_URL (loopback; server/routes/api/[...].ts). The token never reaches the browser; the browser only ever holds the session cookie. (The host also binds the read-only surface — host status + the game library — to the LAN so paired native clients can fetch it directly over mTLS; that path uses client certs, not the token, and never touches this console.)

So: browser ──password──▶ web server (session cookie) ──mgmt token, server-side──▶ mgmt API. Run the host with a matching token: cargo run -rp punktfunk-host -- serve + PUNKTFUNK_MGMT_TOKEN=… (or --mgmt-token …). vite dev has no gate (localhost-only) and proxies straight to the loopback mgmt API.

Toolchain notes (load-bearing): TanStack Start's start-plugin-core peer-requires Vite ≥ 7 — on Vite 6 the build's prerender/post-build hook silently doesn't run. @vitejs/plugin-react must match Vite (v5 ↔ Vite 7, v6 ↔ Vite 8); it's required even for dev (TanStack Start's dev mode needs the React Refresh runtime, else a blank screen). Nitro is the server target — without it vite build only emits client+SSR bundles, no deployable server. The Nitro bun preset makes .output/server/index.mjs Bun-runnable.

Codegen

Generated code is not committed (gitignored) — reproduced from sources:

  • bun run codegen — regenerate the API client (orval) + i18n runtime (paraglide). Runs on bun install (prepare) and before dev/build (pre* for orval; the Vite plugin compiles paraglide on dev/build).
  • After a management-API change, regenerate the spec on the Rust side first: cargo run -p punktfunk-host -- openapi > api/openapi.json, then bun run api:gen.
