832ebe9cd6Adds a full in-browser editor for authoring custom starting
layouts and a persistent library to save them across sessions.
persist/layout-library.ts:
- SavedLayout shape with id/name/pieces/starred/updatedAt.
- saveToLibrary / loadLibrary / deleteFromLibrary / setStarred /
duplicateEntry / makeId helpers.
- Capacity cap at 20 entries; oldest non-starred is evicted on
overflow; all-starred + full returns { ok: false, reason }
so the UI can surface an actionable message.
- Localstorage key is versioned (houserules:layouts:v1) for a
future migration path.
- 14 unit tests cover eviction, shape validation, star toggles,
duplicate flow, and the crypto.randomUUID fallback.
ui/LayoutEditor.tsx:
- Modal overlay with three panels — palette (white/black pieces +
Erase + Clear), interactive 8x8 board with click-to-place
brushes, and an actions panel.
- Live FEN textarea (toFen/fromFen round-trips) with a Load
button that replaces the board and a Reset-to-board sync.
- Live validation panel shows errors (block CTA) and warnings
(inform but don't block). The 'Use This Layout' CTA is disabled
until errors clear.
- Save to Library writes a SavedLayout; the integrated Library
drawer lists saved layouts sorted by starred-first + most-recent,
with Load / Star / Duplicate / Delete actions.
- Copy Share Link writes a \${origin}/?fen=...&name=... URL to the
clipboard — pastes straight into the lobby's existing query-param
pre-select flow from Phase D.
- Esc closes the modal.
ui/Lobby.tsx:
- Custom... entry in the layout picker opens the editor.
- onApply(layout) commits the custom layout as the lobby's
current selection so Create Room ships it to the server.
e2e/layouts.spec.ts:
- Picker renders every premade + Custom entry.
- Selecting Dunsany updates description; ?layoutId=dunsany and
malformed ?fen behave correctly.
- Editor opens on Custom, validates king count, erases pieces,
loads FEN, commits via 'Use This Layout', saves to library
with cross-reload persistence, closes on Esc.
1025 unit tests passing; bun run check clean. Playwright suite
requires dev server — run with \`bun run --filter @paratype/chess e2e\`
