 - **`StackDataProvider` interface** — Breaks circular import between the backup packages and stacks. Defined in `internal/appbackup` (and re-exposed via a type alias in `internal/backup`). Implemented by `stackAdapter` in `main.go`. Provides `GetStackHDDPath()` for per-drive backup routing.
 - **Atomic file writes** — All persistent state (`settings.json`, `app.yaml`) written to `.tmp` then `os.Rename` for crash safety.
 - **`go:embed` templates** — All HTML/CSS/JS compiled into the binary. No runtime file dependencies.
+- **Design system v2 (v0.96.0, TASK-D0)** — The whole UI renders in the Felhom v2 language (canonical
+  reference: `felhom.eu/documentation/design/design-system.md`): navy token palette, single 2px radius,
+  no shadows, exception-based status color (nominal = blue/neutral; amber/red only on deviation —
+  `stateColor` emits `run/progress/warn/neutral/off`, `usageColor`/`tempColor` emit
+  `nominal/warn/crit`; a stopped app is neutral, NOT red). Capacity bars are the hairline `.meter`
+  component; state chips are `.tag`; informational pills are `.metarow`. **Fonts (Plus Jakarta Sans +
+  JetBrains Mono, variable woff2, latin+latin-ext) and a 30-icon Lucide sprite are vendored in the
+  binary** (`internal/web/static/fonts/` served at `/static/fonts/`; `templates/icons.html`) — no CDN,
+  no emoji. The setup wizard serves the same embedded stylesheet via `web.StyleCSS()`.
 - **Europe/Budapest timezone** — All scheduled jobs, timestamps, and UI labels use Hungarian timezone.
