Remove the duplication of the ~18 per-hue dynamic tokens between
theme.css and buildThemeTokens(): theme.css now only defines fixed
neutrals, surfaces, layout and z-index; hue/mode-dependent values
come solely from tokens.ts, injected via SSR as an inline <style> in
+layout.svelte (tokensToCss helper) and reapplied on every hue
change. app.html sets data-theme before first paint by reading
localStorage, removing the dark flash when light mode was saved.
The two inline-style backgrounds become @utility
app-backdrop/app-vignette; the main's bottom padding becomes
@utility app-main, driven by --mf-dock-h via [data-has-track].
Note: <style>{expr}</style> doesn't interpolate in Svelte (it
compiles as component-scoped CSS) — the SSR block is injected with
{@html `<style>${css}</style>`} since the content is fully generated
(no user input).
Verified in the browser: --mf-accent/--mf-bg resolve correctly during
SSR, data-theme='light' applies before the first render with no
flash.
web-player
Musify's web client: SvelteKit 2 (adapter-node), Svelte 5 runes, Tailwind 4,
TypeScript. Authentication is server-side OIDC against Zitadel (openid-client
and jose) with an encrypted session cookie; the backend is called from load
functions and form actions through a typed openapi-fetch client.
Development
npm install
npm run dev # :5173
Configuration lives in .env (template in .env.example). Bring the
infrastructure stack up first (see ../deploy/README.md)
and copy the WEB_CLIENT_ID / WEB_CLIENT_SECRET it writes to deploy/.env
into this .env once, then run the dev server.
npm run check # svelte-check — must be clean before closing a change
npm run lint # prettier --check . && eslint .
npm run format # prettier --write .
npm run build # production build into build/
npm run gen:api # regenerate src/lib/api/schema.d.ts from the running API
Production
Built and run as a container by the production stack — see
../deploy/README.md. There the same variables come from
deploy/.env.prod through compose instead of from .env.
Conventions and the design system are documented in CLAUDE.md and
in the musify-web skill.
