Add a pre-boot "potato check" for the standalone editor: probe the device
against what the KiCad WASM tools actually require and warn (or block, with an
override) before the expensive WASM asset fetch.
- preflight/capabilities.ts: pure, unit-testable probe → CapabilityReport with
stable codes. Fatal: no SharedArrayBuffer/cross-origin-isolation, no
WebAssembly, no Workers+Atomics, no WebGL2. Warn: low deviceMemory, low JS
heap limit (Chromium), few cores, mobile, small screen. Thresholds in one
tunable const block.
- preflight/BlockingDialog.tsx: reusable modal blocking overlay (no dismiss
except via explicit action) — also for feature 0002's terminal dialog.
- preflight/PreflightGate.tsx: runs the probe once on mount; fatal → blocking
dialog with "Try anyway" (short-circuits the asset fetch); warnings →
dismissible advisory banner with localStorage "don't show again" keyed to the
exact warning codes.
- ToolPage: wrap WasmTool in PreflightGate so the gate runs before boot.
Optional micro-bench (phase 3) deferred per the spec.

Generalize the collab transport into a provider registry (none |
broadcastchannel | partykit | hocuspocus), one active per env. startCollab
takes { provider, room } and awaits provider.whenSynced() before seed/adopt.
Network libs lazily imported; room id from @pcbjam/shared collabRoomId.

Reduce web/ to a single generic editor app plus a minimal example backend,
moving all project-specific/app code out to the closed root repo:
- apps/frontend -> standalone (@pcbjam/standalone): the GPL editor. Strips the
project-management UI (ProjectsPage/ProjectDetailPage/UploadDropzone and the
write half of lib/api.ts). WasmTool now takes fetchBytes + assetBaseUrl as
injected props (decoupled from the API client) so it can be driven by either
a backend or a local folder. New HomePage (local-folder loader + backend
project list) and read-only ProjectView. BroadcastChannel collab unchanged.
- backend (@pcbjam/backend-example): thin Fastify+ts-rest reference impl of the
@pcbjam/shared contract — serves a single project off the local filesystem
(PROJECT_DIR), no DB/auth/uploads.
- packages/contract -> web/pcbjam-shared (git submodule, MIT @pcbjam/shared).
- Remove apps/server, packages/storage, packages/contract, docker-compose
(server + storage move to the closed root repo; preserved via subtree
branches). Rewrite pnpm-workspace/turbo/.env for the frontend-only layout.
- Add tests/fixtures/demo so the editor + example backend run out of the box.
Standalone typechecks + builds; backend serves the contract end-to-end.
