chore: scaffold Vite + TypeScript with GitLab Pages CI

Vanilla TypeScript with no UI framework: the app is a few canvases and a
control panel sharing one small state object, and a framework's render model
would fight the drawing loop rather than help it.

CI runs tests and builds on every push, and publishes to Pages from the
default branch. The build takes its base path from CI_PROJECT_NAME so it
works locally and deployed without a second config; BASE overrides it if
Pages ever serves this from a domain root.

world.private.json and dated backups are ignored: they carry the author's
unpublished working notes, and a public repo makes anything in it public
whatever a flag inside the file says.

+# Tower
+
+**Live map — <https://pavelsafronov.gitlab.io/tower/>** · [Source](https://gitlab.com/PavelSafronov/tower)
+
+Companion piece to a novel set inside **Tower** — a fictional smart cylinder orbiting Earth,
+spun for 1 g, with an inner surface the size of Wisconsin, lit by 54 TW of sunlight
+piped down its axis and scattered by mirrors that make its days and nights. The hull
+is sealed: no windows, no stars, no view of the Earth it orbits — only a pinwheel of
+stars through the windows at the far cap.
+
+Explore Tower from outside, pick a spot on the inner surface, and stand there while
+the light shifts and the stars wheel past every seven and a half minutes. Turn its
+sun up to Earth clear-sky noon, or down to permanent dusk.
+
+Tower flies all 78 billion mirrors of its own sunlight, individually, because
+nothing passive would stay in the beam past mid-afternoon. It is a person.
+
+## Status
+
+**Phase 6 — writer mode.** The map and the world file work end to end; the 3D
+exterior and interior views are still ahead.
+
+Built: unrolled surface map with slats and land strips, place editing for six kinds
+(points and polygons), a runtime slat-count control (0–16), localStorage autosave,
+backup and static exports, import, and the sightline probe.
+
+- [design.md](design.md) — canon, physics and application architecture
+- [decisions.md](decisions.md) — choices made and why
+
+Both are series-bible material: coherence outranks spectacle, and the prose is
+downstream of them.
+
+## Development
+
+```
+npm install
+npm run dev      # http://localhost:5173
+npm test         # 63 tests; canon figures are pinned to design.md
+npm run build
+npm run terrain   # regenerate the maps from content/geography.json
+```
+
+Vite + TypeScript, deployed to GitLab Pages by `.gitlab-ci.yml` on every push to the
+default branch. Three.js arrives with the 3D views.
+
+`vite.config.ts` takes its base path from `CI_PROJECT_NAME`, which gives `/tower/`
+— correct for `https://pavelsafronov.gitlab.io/tower/`. If GitLab assigns this
+project a *unique* Pages domain instead (served at the root), set a `BASE=/` CI
+variable and the build will follow.
+
+## Geography
+
+[`content/geography.json`](content/geography.json) is the authored source of truth
+for terrain — coordinates in canon (θ, z), elevations in metres above the base
+shell. `npm run terrain` renders it, with no dependencies beyond Node:
+
+| | |
+|---|---|
+| `public/terrain-height.png` | 16-bit greyscale, 0–5,000 m |
+| `public/terrain-color.png` | the whole world, 264 m/px |
+| `public/terrain-corridor.png` | the developed corridor, 122 m/px |
+| `public/world.json` | seed places for the app |
+
+It reports each stage as it goes — every relief op, colourisation, and PNG encode —
+and takes about 6 seconds. Flags:
+
+| | |
+|---|---|
+| `--probe <theta>` | print elevation jumps along a row, for checking river gradients and finding discontinuities |
+| `--quiet` | one line per stage instead of one per feature |
+| `--force` | let the seed overwrite places added in the app |
+
+## Reading and writing
+
+The map opens in **writer mode**: tools, editor, canon controls and import/export.
+Add **`?reader=1`** to preview what a reader gets — the terrain, the places, a
+detail card and the sightline probe, with no editing. Writer is the default while
+the world is still being built; that is a one-line change when it is ready to
+publish. Either way it is a UI mode, not a security boundary — with no backend an
+editor can only change their own copy (decisions.md D-011).
+
+Any selection updates the URL, so a link is always shareable:
+
+| | |
+|---|---|
+| `#place=the-narrows` | select and centre a place |
+| `#at=0.03,170000` | drop a sightline endpoint at (θ, z) |
+
+## Working in the map
+
+Pick a tool, click to place; **Lake**, **Forest**, **Desert** and **Region** trace a
+polygon and **River** and **Canyon** trace an open line (Enter finishes, Esc
+cancels). Drag markers to move them, **shift-click two points** to
+measure a sightline, **f** to fit the view.
+
+**Star slats** under Canon changes the count from 0 to 16. Canon is **0** — the hull
+is sealed, the inner surface is one unbroken 169,646 km², and the only views out are
+at the end caps. The control is kept as an exploration tool: with slats, the total
+width is fixed, so land stays exactly Wisconsin's 140,268 km² at every count from 1
+up and only the per-slat width moves.
+
+Everything autosaves to this browser's localStorage. Two exports:
+
+| | |
+|---|---|
+| **Export backup** | everything, private notes included. Keep out of the public repo — `.gitignore` already excludes `tower-backup-*.json`. |
+| **Export static map content** | public places only, `notes` stripped. This is `public/world.json`, the world readers see, and the seed for a browser with no local draft. |
