    Boot raycaster race fix: queue pre-ready canvas clicks + replay on ready (durable)
    
    The canvas click listener is wired at init() but wingBoards stays empty until the
    async loadProducts()->buildWingWall() chain finishes (~2-3s). A click in that window
    used to silently no-op (empty raycaster targets) — to a 65-year-old that reads as
    'it's broken.' Now:
    
    - wingWallReady flips true the instant the full 50-board bank is wired into the
      raycaster (end of buildWingWall).
    - onCanvasClick, when not ready, QUEUES the click coords (latest wins) and shows a
      gentle 'Loading the collection — your selection is queued…' cue via the existing
      loader status — never a dead click.
    - drainBootClick() replays the queued click as the FINAL boot action (+2600ms, after
      the version engine's boot-time V1 apply), through the exact onCanvasClick path, so
      the board the user pointed at is selected + conveyored-to-front + 4-wall clad +
      detail shown. Their click WINS, durably.
    - enterGuidedDefault / enterFixedCentre yield to a consumed/pending boot click during
      the boot window (_bootClickConsumed / _bootFixedCentreYield) so the resting-middle
      re-asserts and the versions.js V1 build cannot stomp the user's selection.
    
    No Slice-1/2/3 regression: slice1 PASS (resting-middle, posDelta 0, clamp ±72°, 50
    boards, errorCount 0), slice2 PASS (boot no-clad, select allFourClad, posDelta 0).
    Proof: scripts/verify-bootrace.mjs — pre-ready click queued+cue shown, replay selects
    board durably (allFourClad, detail visible), normal click no-regression, errorCount 0.
