+ * one kind of module, and each file is named after its domain:
  *
- * - **Entry point** — builds the application and listens:
- *   [main](./api/main.ts/index.html).
- * - **Routes** — the HTTP API; each router's page lists its endpoints:

- *   [bandcamp](./api/routes/bandcamp.ts/index.html),

- *   [ws](./api/routes/ws.ts/index.html),
- *   [youtube](./api/routes/youtube.ts/index.html).
- * - **Middleware** — what runs around every route:
- *   [auth](./api/middleware/auth.ts/index.html),
- *   [error](./api/middleware/error.ts/index.html),
- *   [og](./api/middleware/og.ts/index.html).
- * - **Services** — the logic and every SQL query, one module per domain:
- *   [attachment-service](./api/services/attachment-service.ts/index.html),
- *   [backlink-service](./api/services/backlink-service.ts/index.html),

- *   [0016_performance_indexes](./api/db/migrations/0016_performance_indexes.ts/index.html).
- * - **Settings and scripts**: [config](./api/config.ts/index.html),
- *   [generate-icons](./api/scripts/generate-icons.ts/index.html).
+ * - `routes/` — the HTTP API. Each router's page lists its endpoints: method
+ *   and path, who may call it, what it does.
+ * - `middleware/` — what runs around every route: auth, errors, OG tags.
+ * - `services/` — the logic and every SQL query, one module per domain.
+ * - `model/` — per table, its row type, guard and mappers.
+ * - `validators/` — the request-body guards.
+ * - `remote/` — the only place that fetches from other sites; its `providers/`
+ *   build the previews of each kind of site.
+ * - `lib/` — helpers that belong to no layer.
+ * - `db/` — the handle, its creation, migration and startup housekeeping;
+ *   `db/migrations/` are applied in order, each once.
+ * - `config.ts` — the settings read from the environment; `scripts/` — the
+ *   icon generator.
  *
  * ## Shared — `shared/`
  *
- * The types and constants both halves use: the API envelope, each domain's
- * types and request bodies, the socket protocol, the validation limits and the
- * role permissions. It imports nothing from either half.
- *
- * Modules: [api](./shared/api.ts/index.html),
- * [category](./shared/category.ts/index.html),
- * [chat](./shared/chat.ts/index.html),
- * [comment](./shared/comment.ts/index.html),
- * [dump](./shared/dump.ts/index.html), [follow](./shared/follow.ts/index.html),
- * [mention](./shared/mention.ts/index.html),
- * [notification](./shared/notification.ts/index.html),
- * [permissions](./shared/permissions.ts/index.html),
- * [player](./shared/player.ts/index.html),
- * [playlist](./shared/playlist.ts/index.html),
- * [search](./shared/search.ts/index.html), [user](./shared/user.ts/index.html),
- * [validation](./shared/validation.ts/index.html),
- * [ws](./shared/ws.ts/index.html).
+ * The types and constants both halves use, one module per domain: the API
+ * envelope, each domain's types and request bodies, the socket protocol, the
+ * validation limits and the role permissions. It imports nothing from either
+ * half. The server sends `Date`s; the client reads the same types through
+ * `Wire<T>`, with every `Date` an ISO string.
  *
  * ## Frontend — `src/`
  *
- * The React app, built with Vite and translated with Lingui. Each layer holds
- * one kind of module, and every layer but pages/ is split into the same domains
- * (auth, category, chat, comment, dump, editor, feed, form, layout, player,
- * playlist, profile, social, theme, ws, and shared for what belongs to no one
- * domain). A page reads the API and the socket through contexts and hooks, and
+ * The React app, built with Vite and translated with Lingui. `main.tsx` mounts
+ * it, `App.tsx` holds the providers and the route table, `i18n.ts` the
+ * language. A page reads the API and the socket through contexts and hooks, and
  * draws with components; utils hold what isn't React at all.
  *
- * - **Entry point and app** — mounting, the providers and the route table, the
- *   language: [App](./src/App.tsx/index.html),
- *   [i18n](./src/i18n.ts/index.html), [main](./src/main.tsx/index.html).
- * - **Pages** — one component per route, each naming it, and the two guards
- *   that wrap the routes for the signed in and the signed out:
