/**
 * Life Journey — the real board: 211 tiles across 12 segments, built from
 * shared/tileInventory.js (parsed from the design doc).
 *
 * TEMPORARY: the 12 segments have no defined connections yet — that's what
 * shared/BRANCHING-TEMPLATE.md is an open request for (the STOP forks, and
 * which segment's exit feeds which segment's entry). Until board-graph.json
 * exists, TEMP_SEGMENT_ORDER below just concatenates all 12 segments in the
 * design doc's own listed order into one line, so movement/tests/rendering
 * have something real to walk. This is NOT the real board topology — delete
 * this placeholder and replace `next` wiring once board-graph.json exists.
 *
 * Similarly, no tile in the source data has type 'finish' (win condition is
 * itself an open question in GAME-REVIEW.md) — a synthetic `finish` space is
 * appended after the last tile so the reducer has something to end on.
 *
 * Movement is one tile per turn (no tile in the data implies a movement die —
 * every `die` value belongs to that tile's own effect resolution), so unlike
 * the old board there is no walkForward()/multi-step-with-early-stop concept
 * here: a turn is just "go to `next`, then resolve whatever that tile needs."
 *
 * Space shape: { id, type, label, die, externalTables, statsTouched, next }
 *   type: one of the 9 tile-inventory types — payday, action_space,
 *     dice_space, roll_table_ref, inline_table, cash_bonus, event, choice, stop
 *   die: 'D100'|'D20'|'D10'|'D8'|'D6'|'D2'|null — what to roll to resolve this tile
 *   externalTables: source_doc_id[] into shared/rollTables.js (0-3 entries)
 *   statsTouched: string[] hint from the source data, informational only
 *   next: id of the following space (absent only on the synthetic 'finish')
 *   choices: NOT set on any tile yet (no real branch destinations are known) —
 *     shared/game.js only pauses a 'choice'/'stop' space for a decision when
 *     `choices` is non-empty, so today every one of these is a harmless
 *     pass-through, not a dead end.
