ci: add npm run build step to unit-tests job

The prerender fix only prevents regression if the build is actually run in
CI. Without this gate, a future prerendered route that becomes unreachable
behind auth would fail silently until someone runs the build manually.

Fits after the test step in the existing unit-tests job — no new job needed
since node_modules is already cached for the Playwright container.

+
+`AppUser` permissions are already derived in `+layout.server.ts` and exposed via `$page.data` as `canWrite`, `canAnnotate`, and `canBlogWrite`. The home route needs a single boolean to switch its layout and its data fetch set, and that boolean has to be load-bearing — every future permission introduced has to be classified against it.
+
+## Decision
+
+```ts
+const isReader = !canWrite && !canAnnotate;
+```
+
+Computed at the start of `+page.server.ts` `load()`. When true, the loader fetches a lean reader set (stats / top-4 persons / recent docs / recent stories — and drafts when `canBlogWrite`) via `Promise.allSettled` and returns a discriminated-union shape the page distinguishes via `data.isReader`.
+
+`BLOG_WRITE` is **not** part of the discriminant. A `READ_ALL + BLOG_WRITE` user is still a reader and additionally sees the `ReaderDraftsModule`. Story writers are conceptually closer to readers than to transcribers: they consume the archive, occasionally publish narrative on top of it, and have no business with the transcription queue.
+
+A `BLOG_WRITE`-only user (no `READ_ALL`) is also classified as a reader by this formula. Because every reader API requires `READ_ALL`, all four content tiles degrade to empty via `Promise.allSettled`. They see the empty reader shell plus the drafts module — acceptable behaviour, since this permission combination is degenerate by configuration. Documented in `docs/GLOSSARY.md`.
+
+## Alternatives Considered
+
+| Alternative | Why rejected |
+|---|---|
+| New `/reader-home` route with a server-side redirect from `/` | Two routes that mostly answer the same product question (home page). Bookmarks split, breadcrumbs split, header `home` link has to know which to use. The conditional-render keeps a single canonical URL and lets the auth state drive the layout, matching how `canWrite` already gates the upload zone in the contributor branch. |
+| `AppUser.dashboardVariant` column persisted in the DB | Permissions already encode the relevant signal; a separate field has to be kept in sync with permission changes. Drift is a feature foot-gun: a user gets `WRITE_ALL` granted but their `dashboardVariant` field still says `reader` and they keep seeing the wrong UI. |
+| Middleware/handle hook redirecting based on permissions | Same logical issue as the dedicated route plus a network round-trip on every dashboard hit. The discriminant runs once inside the same `load()` that's already fetching the user. |
+| `isReader = !canWrite && !canAnnotate && !canBlogWrite` (exclude `BLOG_WRITE` from readers) | Treats blog writers as contributors. They would land on the `MissionControlStrip` they cannot meaningfully use (no `WRITE_ALL`, no `ANNOTATE_ALL`) and would have to scroll past the transcription queue to find their own drafts. The reader shell + drafts module fits their actual workflow. |
+
+## Consequences
+
+**Easier:**
+- Reader and contributor views share one canonical home URL — no redirect, no routing fork.
+- Adding a new content tile to the reader dashboard is a single-file change inside the `if (isReader)` branch of `load()` plus a new component import in `+page.svelte`.
+- Backend `@RequirePermission(READ_ALL)` on every reader API call remains the load-bearing security gate. `isReader` is purely a UX flag — manipulating it client-side serves a different layout to the same authenticated user with the same permissions.
+
+**Harder:**
+- Every future `Permission` value has to be explicitly classified against this formula. Adding a permission that grants contribution rights but not `WRITE_ALL`/`ANNOTATE_ALL` would silently leave its bearers on the reader dashboard. Mitigation: keep this ADR linked from `+page.server.ts` and from the `Permission` enum's Javadoc.
+- The discriminated-union return type of `load()` (`{isReader: true} | {isReader: false}`) requires every consumer to narrow on `data.isReader` before accessing branch-specific fields. The current `+page.svelte` already does this with the top-level `{#if data.isReader}`; new consumers of the home loader must follow suit.
+
+## Future Direction
+
+If a third cohort emerges (e.g. an admin home with system-health tiles), promote the discriminant to a tagged-union: `dashboard: 'reader' | 'contributor' | 'admin'`. The discriminant computation moves from `+page.server.ts` into a small helper in `lib/shared/server/`, callable from any route that needs the same classification (e.g. a future `/welcome` onboarding flow).
+
+If `BLOG_WRITE`-only access becomes a real product mode (rather than the degenerate combination it is today), revisit whether the formula should add a `canRead` precondition: `isReader = canRead && !canWrite && !canAnnotate`.

+# C4-PlantUML Diagrams
+
+Architecture diagrams in C4-PlantUML format. These are the authoritative source for layout-accurate diagrams. The companion `c4-diagrams.md` in the parent directory keeps Mermaid versions for inline Gitea rendering.
+
+## Render in Gitea
+
+Gitea is configured to render `.puml` files as diagrams. Open any `.puml` file in the Gitea UI to see the rendered diagram.
+
+> **Note:** `plantuml` code fences inside Markdown files do **not** render inline in Gitea — this is a Gitea limitation unrelated to the server configuration. The `.md` files in this repo use Mermaid for that reason.
+
+## Render in VS Code
+
+Install the [PlantUML extension](https://marketplace.visualstudio.com/items?itemName=jebbs.plantuml) (`jebbs.plantuml`). The project's `.vscode/settings.json` already points at the shared server:
+
+```
+plantuml.server = http://heim-nas:8500
+```
+
+Open any `.puml` file and press `Alt+D` to preview.
