Expand the board to the full sketch (~107 spaces, three forks)

shared/board.js now transcribes every distinct space label from the
hand-drawn sketch (assets/game_board.png) rather than Phase 1's small
subset. The sketch's arrows get genuinely ambiguous in a few places (it
reads as a mockup, not an engineered spec) and reuses several space names
across zones (Start A Business, Family Reunion, Market Crash, ...) — that
repetition is kept as intentional flavor rather than deduplicated, and the
ambiguous bits are resolved into a clean DAG with the same shape Phase 1
proved out: a fork, a chain() per branch, a convergence — repeated three
times (Career/Education/Gap Year, then Relationship/Investment, then High
Risk/Safe), into a long shared retirement tail. Branches are built with a
small chain() helper that auto-wires each entry's `next` to the following
one, since hand-wiring ~107 ids was too error-prone.

The reducer, SQLite schema, and rooms/WS layer needed zero changes — the
whole point of the pure-reducer/graph-data design from Phase 1. Two things
did need generalizing:
- public/boardRender.js's lane offset was hardcoded to a 2-way fork; the
  new "Which Path?" fork is 3-way (Career/Education/Gap Year), so the
  offset formula is now symmetric for any number of branches.
- shared/game.test.js hardcoded Phase 1's specific space ids. Rewritten to
  be board-structure-agnostic: it always resolves the first offered choice
  and otherwise rolls the max die value, which reliably makes progress
  regardless of board shape (walkForward always stops early at the next
  choice/finish), plus a graph-well-formedness check.

Verified: unit tests green; a full two-player game played headlessly
end-to-end through all three forks to Finish in 38 turns with zero
console/page errors; the rendered board visually confirmed at full scale
(5-row snake layout, 3-way fork fans out correctly, all labels legible).

-## The board (Phase 1 subset)
+## The board
 
-The full hand-drawn board (`assets/game_board.png`) has ~150 spaces across two
-thematic passes (Career, Education, Gap Year, Relationship/Family,
-Investment, High Risk). Phase 1 encodes a small subset with the same shape —
-a Career-vs-Education fork, a Relationship-vs-Investment fork, a
-High-Risk-vs-Safe fork, converging to Finish — enough to prove the reducer,
-persistence, and rooms all work end to end. More spaces can be inserted into
-any branch later without touching the reducer or database schema.
+`shared/board.js` (~107 spaces) is transcribed from the hand-drawn sketch at
+`assets/game_board.png`, organized into three fork points with the same
+shape the sketch uses: **Career / Education / Gap Year** at the start,
+**Relationship / Investment** after a shared "quarter-life crisis" chain,
+then **High Risk / Safe** before a long shared retirement tail to Finish.
+The sketch reuses several space names across its zones (Start A Business,
+Family Reunion, Market Crash, ...) — that's kept as intentional recurring
+flavor rather than deduplicated. More spaces can be inserted into any
+branch's `chain([...])` array in `board.js` without touching the reducer,
+the SVG renderer, or the database schema — none of them know or care how
+many spaces exist.

- * A small representative subset of the full hand-drawn board (assets/game_board.png):
- * a Career-vs-Education fork, a Relationship-vs-Investment fork, a High-Risk-vs-Safe
- * fork, and a Finish. Same shape as the full sketch — more spaces can be inserted into
- * any branch array later (repointing one `next`) without touching the reducer.
+ * Transcribed from the hand-drawn sketch (assets/game_board.png), which uses
+ * many space names more than once across its zones (Start A Business,
+ * Family Reunion, Market Crash, ...) — that repetition is treated as
+ * intentional recurring flavor, not deduplicated. The sketch's arrows get
+ * genuinely ambiguous in a few spots (a hand-drawn/AI-generated mockup, not
+ * an engineered spec), so rather than force a literal reverse-engineering of
+ * every arrow, every distinct label from the sketch is kept and organized
+ * into a clean DAG with the same shape Phase 1 already proved out: a fork,
+ * a chain per branch, a convergence, repeated three times, then a long
+ * shared retirement tail. More spaces can still be inserted into any branch
+ * later — just splice into its chain() array below.
  *
  * Space shape: { id, type, label, next?, choices?, cash?, flavor? }
  *   type: 'start' | 'event' | 'money' | 'choice' | 'finish'
