feat: gallery + generic blueprint viewer, add Grid blueprint

Refactor the List-specific screen into a data-driven, reusable viewer:
- generic Blueprint type + shared LoadState machine + registry
- vue-router: / (gallery) and /b/:slug (illustration)
- BlueprintViewer renders any blueprint; specimens stay bespoke
- add Grid blueprint (6 functions incl. Position) + GridSpecimen

+# Context — ubiquitous language
+
+The shared vocabulary for `blueprints`. These terms should appear verbatim in
+conversation, code, file names, and commits. This file is a glossary only — no
+implementation details (those live in `DESIGN.md`).
+
+## Blueprint
+
+A named contract for a recurring UI pattern, taken from the `blueprint-ontology`
+repo — declarative, categorical, abstract (a _concept_ in Jackson's sense). It
+defines what must be true of the pattern: its signature, state machine, behaviors,
+invariants, functions, critical-performance thresholds, and failure modes. Examples:
+`List`, `Grid`, `Table`, `Async`.
+
+Blueprints come in two roles (from the ontology):
+
+- **Feature** — a standalone pattern a user interacts with (`List`, `Grid`, `Form`).
+- **Capability** — a composable blueprint that adds state/behavior onto a host
+  feature (`Async`, `Paginated`, `Selectable`).
+
+## Illustration
+
+This app's rendered, interactive presentation of a single blueprint. `blueprints`
+is a gallery of illustrations. "Illustration" is the noun for the whole per-blueprint
+screen; do not use "demo" (implies a live working widget — these are static) or
+"page" (routing concept, not domain).
+
+## Viewer
+
+The one reusable component that renders any blueprint's illustration. It draws the
+generic parts from a blueprint's typed data and slots in that blueprint's bespoke
+Specimen. Every illustration is the Viewer applied to one blueprint.
+
+## Specimen
+
+The interactive-looking but **static** visual mock of the blueprint's actual UI —
+the left pane of the Viewer. Bespoke per blueprint (a Grid specimen looks nothing
+like a List's). Selecting a Function highlights the region of the specimen that
+function owns. Not "mockup", not "demo".
+
+## Readout
+
+The right pane of the Viewer: the blueprint's formal contract for the selected
+Function — source capability, responsibility, state touched, behaviors (pre →
+effect), invariants, failure modes, critical-performance thresholds.
+
+## Companion
+
+A supporting schematic shown below the Viewer's two panes. Two kinds exist so far:
+the **composition map** (how a feature extends/composes with capabilities) and the
+**state machine** (the blueprint's lifecycle). A blueprint may have neither, one, or
+both.
+
+## Function
+
+One row of a blueprint's "Functional analysis" — a named responsibility of the
+pattern (e.g. List's `Display`, `Scroll`, `Load`). Functions are the unit the Viewer
+lets you explore, tab by tab. Distinct from **Behavior** (a concrete state
+transition like `loadMore()`); behaviors are the mechanics underneath a function.
+
+## Gallery
+
+The app's index (landing screen): every blueprint in the ontology, each as a card
+linking to its illustration — including blueprints not yet illustrated, shown as
+**planned**.

+# Design — `blueprints`
+
+Decisions for building `blueprints` out from a single List illustration into a
+gallery of many. Terminology: see [CONTEXT.md](CONTEXT.md).
+
+## D1 · Content sourcing: hand-authored typed data + bespoke specimen
+
+Each blueprint is a **typed TS data module** (`src/data/<name>Blueprint.ts`),
+transcribed by hand from its ontology README, paired with a **bespoke Specimen**
+component. The generic **Viewer** renders everything else (Readout, composition map,
+state machine) from that data.
+
+- **Why not parse the ontology at build time?** The Specimen must be hand-built for
+  every blueprint regardless (the ontology only provides an ASCII sketch), so parsing
+  would automate only the cheap, structured text — at the cost of fragile
+  markdown/mermaid parsing and a build-time coupling to the ontology repo's exact
+  format. Not worth it.
+- **Source of truth** stays the `blueprint-ontology` repo; the data modules are a
+  faithful transcription, cited in each module's header.
+
+Structural split this implies:
+
+| Part                               | Generic (data-driven)                | Bespoke (per blueprint)             |
+| ---------------------------------- | ------------------------------------ | ----------------------------------- |
+| Chrome (title block, tabs, legend) | ✓                                    |                                     |
+| Readout (dossier per function)     | ✓                                    |                                     |
+| Composition map                    | ✓ (from `extends` + `composes` data) |                                     |
+| State machine                      | ✓ (from nodes/edges data)            |                                     |
+| Specimen                           |                                      | ✓ component slotted into the Viewer |
+
+## D2 · Routing: vue-router, URL per blueprint
+
+Add `vue-router`. Routes: `/` → Gallery, `/b/:slug` → the blueprint's illustration
+(e.g. `/b/list`). Deep-linkable and shareable; browser back/forward works. The nginx
+SPA fallback (`try_files … /index.html`) already serves client routes, so no server
+change is needed. A blueprint registry (`src/data/blueprints.ts`) maps `slug →
+{ data module, specimen component, meta }` and is the single source both the router
+and the Gallery read from.
+
+## D3 · Gallery: illustrated-only, grows over time
+
+The Gallery lists **only** blueprints that have an illustration; it grows as we add
+them. No greyed "planned" cards. Rationale: keeps the landing clean and truthful, and
+avoids maintaining metadata for 45 not-yet-built entries. A blueprint appears in the
+Gallery precisely when it is registered in `src/data/blueprints.ts`.
+
+## D4 · Build-out slice #1: foundation + Grid
+
+**Foundation (refactor, no UX change to List):**
+
+- `pnpm add vue-router`; `App.vue` → thin shell with a header (link home) + `<RouterView/>`.
+- `src/views/GalleryView.vue` (`/`) — cards from the registry.
+- `src/views/BlueprintView.vue` (`/b/:slug`) — resolves the registry entry, renders the Viewer.
+- `src/components/BlueprintViewer.vue` — the **generic Viewer**, generalized from the
+  current List-specific `App.vue`: title block, legend, function tabs + full view,
+  two panes, optional composition map + state machine, footer. Props: a `Blueprint`
+  object + the blueprint's Specimen component (injected via `<component :is>`).
+- Generic `Blueprint` type in `src/data/blueprint.ts` (signature, functions,
+  coreInvariants, optional composition, optional stateMachine, meta). `listBlueprint.ts`
+  conforms to it. Specimens move to `src/specimens/`.
+- `src/data/blueprints.ts` — registry: `slug → { meta, blueprint, specimen }`.
+
+**Content:** `gridBlueprint.ts` + `src/specimens/GridSpecimen.vue` (2D tile grid).
+
+**Ships:** Gallery listing List + Grid; `/b/list` (same UX, refactored) and `/b/grid`.
+
+**Gates before push:** `pnpm build` clean · `pnpm lint` · `pnpm fmt`; then commit → push
+(auto-deploys) → verify `https://blueprints.apoena.dev`.
+
+Subsequent slices add one blueprint each (Table, Feed, …).
