Fix 1: SliceIds now projects the File id during Select rather than calling
TryGetValue twice (once in Where, once in the local File() helper). Added a
comment noting that OrderBy is stable so X-tie order follows insertion order.
Fix 2: BuildMeter emits a [D.2b] Console.WriteLine when the Type-3 container
count is not exactly 2, surfacing malformed or non-vitals meter elements during
Task 8 conformance testing without disturbing the existing solid-color fallback.
Fix 3: Test 5 adds two explicit NotEqual assertions confirming the
ShowDetail-only overlay sprite (OverlayFile = 0x06007490) did not leak into
FrontRight or FrontTile.
5/5 tests pass, 0 warnings.
