Fix 1: replace 3 copy-paste meter blocks in VitalsTree_MetersHaveExpectedSliceIds
with a single table-driven loop — a 4th meter is now a one-liner and failures
name the failing meter id directly.
Fix 2: FixtureLoader now reads the fixture as bytes and strips the UTF-8 BOM
(EF BB BF) before passing the span to JsonSerializer, so a BOM-bearing fixture
file never causes a spurious JsonReaderException.
Fix 3: add [Trait("Category", "Conformance")] at the class level so conformance
tests are selectable by category filter.
Fix 4: add missing <param name="layoutId"> doc tag to LayoutImporter.ImportInfos.

Job 1: extract LayoutImporter.ImportInfos() (public dat-shell half that returns the
resolved ElementInfo tree without building widgets) so fixture generation and
conformance tests can call it directly. Import() now delegates to ImportInfos() +
Build() — existing 32 Layout tests stay green.
Job 2: generate tests/AcDream.App.Tests/UI/Layout/fixtures/vitals_2100006C.json
from the real portal.dat via a throwaway [Fact] generator (deleted, not committed).
System.Text.Json with IncludeFields=true — ValueTuple serializes as Item1/Item2.
Pre-write validation confirmed health meter BackLeft=0x0600747E FrontRight=0x06007483
rect (5,5,150,16). Round-trip deserialization re-validated before writing.
Job 3: FixtureLoader.LoadVitals() deserializes the fixture from the test output
directory (CopyToOutputDirectory item in csproj) and returns ImportedLayout via
LayoutImporter.Build(root, _ => (0,0,0), null) — no dats, no GL.
Job 4: LayoutConformanceTests — 3 golden tests (35 asserts total):
- VitalsTree_HasThreeMetersAtExpectedRects: 3 meters at x=5, w=150, h=16, y=5/21/37
- VitalsTree_MetersHaveExpectedSliceIds: all 18 back+front slice ids health/stamina/mana
- VitalsTree_ChromeCornerHasExpectedSprite: TL corner 0x10000633 → sprite 0x060074C3
Full App suite: 326 pass / 1 skip (pre-existing) / 0 fail. Build: 0 errors, 0 warnings.
Throwaway generator not committed (confirmed via git status).
