Layout reshuffle so the scene captures the maximum viewer area: - Header collapses three rows into one: `back to map` / `back to report` on the left, the centred title `Battle on planet <name> (#<number>)` (new i18n key `game.battle.header_title`), and the frame counter on the right. The wrapper `.active-view` no longer renders its own back-row; routes flow through props. - Viewer drops the `max-width: 880px` cap so on a wide monitor the scene scales up across the full active-view-host. - A drag-seek `<input type="range">` sits between the scene and the controls; dragging pauses playback and lands `frameIndex` on the chosen shot. - Speed control is one cycling button: `1x → 2x → 4x → 6x → 1x`. The label shows the current speed; the new 6x adds a 67 ms frame interval for skimming a long timeline. - The text protocol log is now collapsible behind a `Log ▲▼` toggle in the controls bar. The toggle is its own button; the default state stays expanded. Collapsing the log hands the remaining height to the scene. - Numerical list markers (`1. 2. 3.`) are dropped from the log; `list-style: none` keeps each row visually clean. Static cluster + visibility filter: - `staticBucketsByRace` now locks bucket order, mass, radius and local Vogel-spiral positions for the lifetime of the viewer; it only re-derives when `report` or the wasm `core` change. - `renderedByRace` overlays the per-frame `remaining` map and drops buckets whose `numLeft` hits zero. The surviving buckets keep their slots, so a class emptying never reshuffles the cluster — the empty bucket simply disappears. - A shot whose attacker or defender bucket is no longer visible draws no line (phantom shots into already-empty buckets are silently skipped, matching the user expectation that pup at 0 should stop attracting fire visually). - Race label clamps to a minimum y inside the SVG viewport so three-or-more-race layouts with a north anchor never clip the top race name off-canvas. Duel layout (user suggestion): - `layoutRaces` rotates the radial start angle by 90° when only two participants remain, so race 0 lands at 9 o'clock and race 1 at 3 o'clock. The pair faces off horizontally; neither label pushes against the SVG top edge. The existing test for two-race positions is updated accordingly. Tests: the existing `layoutRaces` two-race case is rewritten for the horizontal duel; the `game-shell-stubs` battle case checks the loading placeholder (back buttons now live in the loaded viewer, not the wrapper). 644 Vitest cases stay green; 4 Playwright battle-viewer cases stay green. Docs: `ui/docs/battle-viewer-ux.md` documents the static cluster / visibility filter, the duel layout, the scrubber, the cycling speed button and the collapsible log.

ui — Galaxy Cross-Platform Client
ui/ hosts the new cross-platform Galaxy client. A single
TypeScript + Svelte source tree builds to five targets: web,
web-mobile, standalone PC (mac/win/linux), iOS, and Android. A
shared Go module (ui/core) carries envelope cryptography, the
FlatBuffers codec, keypair management, and a thin bridge over
pkg/calc/ for UI-side game math; it is compiled to WASM for the
web targets, gomobile native libraries for mobile, and embedded
directly in Wails on desktop. All network I/O lives on the
TypeScript side via ConnectRPC, so the Go module is a pure compute
boundary on every platform.
The legacy Fyne client under client/ is reference-only.
Nothing in ui/ imports from it.
The full staged implementation plan lives in PLAN.md. The
strategic rationale (why Svelte, why PixiJS, why Go-as-WASM, why
Wails+Capacitor) lives outside the repo at
~/.claude/plans/buzzing-questing-fountain.md. This README is a
quick orientation; deeper per-phase design notes earn their place
under ui/docs/ as they are introduced.
Targets
| Target | Wrapper | Toolchain | Phase |
|---|---|---|---|
| web | browser tab | Vite + WASM | 5+ |
| web-mobile | mobile browser | Vite + WASM | 5+ |
| desktop (mac) | Wails v2 | Go + Wails CLI | 31 |
| desktop (win) | Wails v2 | Go + Wails CLI | 31 |
| desktop (linux) | Wails v2 | Go + Wails CLI | 31 |
| iOS | Capacitor | gomobile + Xcode | 32+ |
| Android | Capacitor | gomobile + Gradle | 32+ |
Layered architecture
- TypeScript + Svelte 5 frontend, shared across all five targets, scaffolded with SvelteKit + Vite.
- PixiJS v8 with dual WebGPU/WebGL backend for the world map renderer.
- Go module
ui/core/as a compute-only library (canonical bytes, Ed25519 sign/verify, FlatBuffers codec, keypair, thin bridge topkg/calc/) compiled to WASM, gomobile, and Wails-embedded native. - TypeScript-side
Coreinterface with three adapters (WasmCore,WailsCore,CapacitorCore) selected at build time. GalaxyClienton top ofCoreperforms all network I/O via ConnectRPC (@connectrpc/connect-web) on every platform.- Per-platform storage: WebCrypto + IndexedDB on web, OS keychain
- SQLite on desktop, iOS Keychain / Android Keystore + SQLite on
mobile, all behind a single
KeyStoreandCacheTypeScript interface.
- SQLite on desktop, iOS Keychain / Android Keystore + SQLite on
mobile, all behind a single
- Mobile-first navigation: one active view occupies the main area at a time; the sidebar holds a single tool (calculator, inspector, or order) with persistent state on switch.

Build pipeline
Every cross-target build flows through make at this level. All
named targets are placeholders until the named phase lands; running
make with no arguments prints the current placeholder map.
make web Vite production build Phase 5+
make wasm TinyGo → core.wasm Phase 5
make ts-protos Connect-ES + Protobuf-ES gen Phase 5
make fbs-ts FlatBuffers TS bindings via flatc Phase 8
make gomobile gomobile bind → ios + android Phase 32+
make desktop-mac Wails build for darwin Phase 31
make desktop-win Wails build for windows Phase 31
make desktop-linux Wails build for linux Phase 31
make ios Capacitor + xcodebuild Phase 32+
make android Capacitor + gradle Phase 32+
make all every target above
Local development
For UI work against a real stack, the tools/local-dev/ docker
compose brings up postgres + redis + mailpit + backend + gateway in
one command, and ui/frontend/.env.development is already wired to
talk to it:
make -C tools/local-dev up # build + start, wait for healthy
pnpm -C ui/frontend dev # Vite on the host
# UI: http://localhost:5173
# Mailpit: http://localhost:8025
The stack accepts a fixed dev code (123456) in addition to the
real Mailpit-delivered one. Full runbook in
../tools/local-dev/README.md.
Per-phase docs
Topic docs live under ui/docs/ and are added per phase as they're
needed (testing tiers, WASM toolchain, navigation shell, renderer
internals, sync protocol, auth flow, and so on). The staged plan in
PLAN.md names the topic doc each phase produces.
